Description
Viva Books Metallurgy of Pure Metals 2009 Edition by J. Drapala
Metallurgy of pure metals is concerned with the refining and preparation of high-purity substances, with special emphasis not only on the high degree of chemical purity attainable by chemical or physical methods (hydrometallurgy, sorption, extraction, crystallisation from aqueous solutions, electrolysis) and also by pyrometallurgical methods (crystallisation from melts, evaporation, condensation and transport reactions, electrotransfer, diffusion separation of substances, removal of gases from metals, and vacuum refining of metals). The main material parameter which is in fact a measure of the separation of impurities during crystallisation processes is the distribution coefficient. Special attention is given in the book to the determination of this coefficient, its properties and correlation with the proton number. An appendix contains the values of distribution coefficients and binary diagrams, mainly for copper, aluminium, iron and its transformation, selected noble, refractory, radioactive metals, lanthanides, and semiconductors.About Author:S Prof. Jaromir Drápala is a Professor at the VSB-Technical University in Ostrava where he lectures in non-ferrous metallurgy, metallurgy of high-purity metals and special alloys, metallurgy of semiconductors, physical metallurgy of metals and materials for electrical engineering. His research interests also include theoretical and experimental studies of the distribution coefficients of elements in metals and semiconductors, simulation of processes of directional solidification and zone melting, simulation and prediction of the properties of alloys after thermomechanical treatment, examination of diffusion processes and determination of interaction coefficients, vacuum refining of metals by electron beam zone melting and the preparation of single crystals of refractory alloys and their low-alloyed alloys. He has authored or co-authored more than 370 publications (10 monographs, 4 textbooks, 55 articles in foreign journals, 55 articles in Czech and Slovak journals. 200 contributions to conference proceedings, etc.)Prof. Dr. Lumir Kuchar (retired) was a Professor at the VSB-Technical University in Ostrava since 1980 until his retirement where he lectured in non ferrous metallurgy, nuclear metallurgy and metallurgy of high-purity metals. In 1964-1966 he worked at the BA Freiberg, ZfW AdW Dresden in Germany and CNRF (Laboratorie des Metaux Purete. Vitry, Paris) in France. The main areas of his scientific-research and lecturing activities are the metallurgy and qualifications and degrees.
