Summary

In new perspective areas of science and technology, as e.g. technology of semiconductors, microelectronics, optoelectronics, technology of superconductive materials, vacuum technology, nuclear metallurgy, space metallurgy and technology, materials, metals and their special alloys and compounds of a high chemical purity with defined physical and structural parameters and specific utility properties are required. The subject "Fundamentals of Metallurgy of Pure Metals" deals with methods of refining and preparation of high purity substances and the stress is laid not only on a high degree of chemical purity attainable by means of chemical and/or hydrometallurgical physicochemical methods, e.g. sorption, extraction, crystallization from aqueous solutions, electrolysis, but also by means of pyrometallurgical methods, such as crystallization from melts, evaporation, condensation and transport reactions, electrotransport, diffusion separation of substances, removing of gases from melts as well as refining of metals in vacuum. When preparing high purity metals by means of crystallization refining methods, zone melting and directional crystallization, which are principal methods of preparation of defined high purity metals, even in the single crystal form, a controlled redistribution of admixtures and impurities present in the basic substance occurs on the melt-crystal phase interface.
