Summary: Extraction of Co(II) and Ni(II) with the commercial
extractantCyanex 272 diluted in kerosene or 2,2,4-trimethylpentane
fromsulphate and sulphate-chloride solutions was studied. Preparedand real
(leach liquor) samples were extracted with 1O % cyanex272 at 25 C using
initial phase volume ratio (organic/aqueous),r(i)= 0.5 and 1.0. A mutual
influence of cobalt and nickel ontheir distribution under certain
conditions was observed. Aneffect of sodium on the distribution ratio of
cobalt was alsofound. In such system at certain conditions three stable
liquidphases were observed. In the heavy organic phase (the thirdphase)
cobalt concentration was higher than in the light organicphase.

Summary: The influence of the solvent composition on the extraction
ofgallium in the systems: (I) GaCl3 - HCl - H2O - Diisopropyl Ether(IPE) -
Hexyl Alcohol and (II) GaCl3 - HCl - H2O - IPE - i-PentylAlcohol was
examined. At equal initial concentration ofhydrochloric acid (5.0 mol.dm-3)
in both systems a strongsynergistic enhancement at 20 per cent vol. content
of alcohol inthe mixed solvent was observed. The maximum value of
synergisticenhancement, expressed as delta-Dc depended on alcohol type
andmetal concentration. In the case of 0.147 mol.dm-3 initialgallium
concentration in system I the value of Dc was about 600and in the system II
about 300. At the same acid concentrationbut at lower initial concentration
of Ga(III) (0.028 mol.dm-3) insystem I a stronger synergisic effect (delta
Dc about 1300) wasfound.

Summary: The catalytic effect of aluminium on the crystalization of
greenpetroleum coke, heat-treated at temperatures 1200-2000 C, hasbeen
studied. The results of investigation crystallite height(Lc) and interlayer
spacing (d002) showed that catalytic effectof alluminium was remarkably
when the metal content was 5% atheat temperature 1500 C. The coking
feedstock influence onstructural parameters changes in crystallization
process has beenalso investigated. These investigation suggest that the
catalyticeffects of aluminium may be greatly influenced by
experimentalconditions, composition of the coke feedstock, the
aluminiumcontent, the heat temperature and so on.

Summary: To determine cerium content in liqwuid extracts recovered
fromnitric acid solutions a suitable quantitative method of analysiswas
required. As conditions of Ce(IV) extraction were examined inpure systems
as well as in the systems wherw the presence ofcerium was accompanied by
that of some other lanthanides from thecerium subgroup (La, Nd, Sm, Eu),
the method had to be fast,simple, selective and readily available. The
possibility ofapplaing x-ray emission spectrometry for this purpose
wasexamined. Among a relative large number of factors influencingthe
sensitivity of x-ray emission spectrometry in this paper theeffect of the
matrix and that of radiation-path medium wereassessed.

Summary: In the scope of the investigation of the integral process
ofrecovery of cobalt(III) from lateritic ore, leaching with mineralacids
and subsequent solvent extraction with Cyanex 272 werestudied. Leaching of
lateritic ore with the mixture of sulphuricand hydrochloric acids at 25 C
had as a result very good recoveryof cobalt(II) and its separation from
nickel particularly athigher concentration level of the acid mixture. The
leaching wasoptimal from the stanpoint of all parameters (temperature
andtime of leaching, percentage of leached metal and separationfactors of
cobalt to nickel and iron). Besides, the medium ofmixed acids made the
subsequent solvent extraction processsimpler and easier to carry out.

Summary: To determine the cause of catalyst deactivation, in
addition tostandard methods of analysis, X-ray diffraction and SEM
wereused. Real and model samples of UOP-R-62 were analysed. Theobtained
diffractometer patterns, FWHM value of the 440reflection of gamma-Al2O3,
electron micrographs and images ofemitted caracteristic X-ray were mutually
compared. Only thevalues obtained from the deactivated catalyst differed
from theothers.Besides reduced broadening of the 440 line the
materialexhibited new X-ray diffraction lines, a chenge in
phasecomposition, and modifications in morphology andmicrostructure. These
changes are an indication that overheatingof individual spheres of catalyst
UOP-R-62 to a temperature of700-1100 C or higher caused their deactivation.

Summary: The influence of a coking crude on the structure of
calcinedpetroleum coke and the subsequent structural changes in cokeinduced
by HTT up to 2400 C were investigated. The surfacemorphology,crystallite
height and interlayer spacing weredetermined as a function of temperature
and heating time. HTT hada positive effect on the coke structure so that
with increasingtemperature and heating time,the crystallite size increased
whilethe interlayer spacing decreased.The results showed that not
onlytemperature but also coking crude were major factors influencingthe
structure of petroleum coke.

Summary: The alloys of chromium and cobalt are widely used in
dentistry as they, considering their mechanical properties, represent the
best substitute for expensive gold alloys. During the production of various
dental appliances, a greater amount of the material is used then required
by size of the appliance itself. The remaining material is often used for
subsequent castings, as a measure of economy.
The aim of the study was the examine the influence of the addition of
various amounts of an already cast alloy on hardness of the alloys of
chromium and cobalt. The properties of the alloys were examined after the
addition of the previously cast alloy in percentages of
0%,25%,50%,75%,100%.
All samples were standardized and cast in a Nautilus (Bego) induction
casting oven. After the treatment, the samples were examined.
The results on hardness and their statistical analysis showed a significant
difference between the examined alloys; the difference of the nature of the
added components contributing more to it then the amount of the already
cast alloy.

Summary: Cobalt-chromium alloys are used in various reconstructive
procedures in prosthodontics. They are most commonly used for metal
constructions of partial prostheses. The casting procedures require more
metal to melt than is needed to fill the cast out. The excess is then
separated from the casting. The possibility of re-usage of this excess
alloy to make a usable casting has been investigated in many studies.
The aim of this experimantal study was to assess the extent of changes
occurring in cobalt-chromium alloys with the addition of various
percentages of pre-cast alloys (B). The Wironium, Wironit (Bego) and Basil
S (Zlatarna Celje) alloys were investigated with addition of 0%, 25%. 50%,
75% and 100% of a pre-cast alloy (B).
Results of the study showed the changes occuring in the metallographic
structure and thus in the chemical composition of the alloys to be within
acceptable limits, indicating the possibility of re-usage of the
cobalt-chromium alloys, with certain limitations.

Summary: To investigate the segregation process and the distribution
of components as a result of briquetting and their influence on the
intensity of the K-alpha lines, samples with components with different
hardness (calcite, scale and quartz) and grain size were prepared, using
boric acid as binder. The results of electron microanalysis confirmed the
presence of the grain segregation process in the briquetted sample. By
measurement of delta-I for each analztical line, the optimal conditions of
briquetting can be obtained.

Summary: Results of measurement of relative intensity of analytical
lines FeK-alpha, CaK-alpha and SiK-alpha in samples of limonite iron ore
and sinter mixture specially prepared samples were studied. The results
obtained showed that changes in relative intensity were due not only to
component participation in each fraction but also to the phase component
participation in each fraction and also to the phase composition of grain,
its behaviour during the briquetting process, segregation rate and the
tendency towards agglomeration and formation of stuck particles.

Summary: Carbon fibre reinforced carbon(CFRC), or carbon-carbon
composites,are unique materials due to their mechanical properties
especially in non-oxidising environments,at temperatures above 2500 C.These
properties,combined with a range of useful physical characteristics like
low density,chemical inertness and bio-compatibility,enable their use in a
wide range of applications.Depending on the sort of carbon fibres,carbon
matrix properties,improvement of oxidation resistance,and fabrication
methods,it is possible to tailor special properties for special
purpose.Obviously,they are materials for the future.

Summary: The influence of microstructure on SSC-resistance of
experimental low alloyed Mn-Mo steel has been studied. The results obtained
revealed close connection of SSC with mechanical properties and
microstructure: resistance to corrosion is decreased while yield strength
and hardness are increased by changing heat treatment conditions.
Differnces in SSC-resistance are consequence of microstructural parameters
like number of phases, grain size, morphological characteristics and
distribution of carbide particles.

Summary: During the production of various dental appliances a
largerammount of material is used then would be required by the actualsize
of the appliance.The purpose of this study was to examinethe influence of
the addition of various amounts of previouslycast alloy (B) on the
hardness,metallographic structure,chemicalcomposition and carbon
concentration of Co-Cr alloys. Theproperties of the alloys were examined
after the addition of thepreviously cast alloy in the percentages of
0%,25%,50%,75% and100%. All samples (Wironium,Wironit,Basil S) were
standardizedand cast in an induction casting machine
(Nautilus,Bego).Theresults of optical microscopy tests show a similar
microstructureof all samples regardless of the nature and an amount of
theadded alloy B.An insignificant increase of all components wasdetected
after chemical analysis without significant effect onthe quality of the
samples.The data regarding hardness and theirstatistical analysis showed a
significant difference between thealloys examined.However the alloy
components contribute more tothis difference then the amount of previously
cast alloy (B).

Summary: The recovery of cobalt by leaching of lateritic ore
(withsulphuric acid, hydrochloric acid and their mixture) andextraction
(with Cyanex 272) of cobalt and nickel from leachliquors and in prepared
samples has been investigated. Theinfluence of temperature, leaching time,
initial ore/acid massratio, initial acid concentration, initial phase
volume ratios,initial pH, and diluent type on the selectivity and
efficiency ofleaching and solvent extraction was found. The method of
removingthe interfering metals was found too. Under certain conditions
ofextraction from sulphate-chloride solution formation of thirdliquid phase
was observed.

Summary: The blast furnace slag is the most frequently used
secondary rawmaterial. In order to enable application of the slag
inconstruction of buildings and perhaps, find some otherapplication,
various chemical properties of blast furnace slagwere examined (by means of
standard procedures ), as well asradiochemical properties (by means of
gamma-spectrometryinvestigation ) and slag phase composition (by means of x
-raysdiffraction method ). Morfology and distribution of elements
ofidentified phases were examined (by means of scanning
electronicmicroscopy), as well as anion exchange properties of blastfurnace
slag in reactions between the slag and series of anions:F(-), Cl
(-),Br(-),NO3(-),NO2(-) and SO4(--) which may influencethe concrete (by
means of ion chromatographic analysis ).By meansof statistic method (Monte
Carlo ),two samples of blast furnacewere chosen and been under temperature
treatment for two hours at200,400,600.800 and 1000 C. 15% of slag treated
in such way ,wasmixed with clinker in cement. The mechanical and
physicalproperties of cement were examined (by means of the
standardprocedures). Extensive slag examination showed stable
chemicalcomposition of the slag,low radioactivity and well-balancedrelation
between acid and basic components.Detailed slagproperties determination by
means of ion chromatography showedthat the slag is a chemically inert
material,whose anions do notelute in the environment. On the other
hand,slag has proved to bea verz good fluoride sorbent,therefore slag
applicationpossibilities,as anew material in technology for treatment
offluoride contaminated water,are extended. Under temperaturetreatment of
blast furnace slag,the share of characteristicglassy phase decreased and
the share of crystalline wasincreased. At 600 C and higher, some new
phases,not identified ininitial samples,appeared. Mechanical properties of
Portlandcement with activated blast furnace slag as admixture, were
notconsiderably changed in relation to Portland cement withadmixture of
inactivated slag.
