Summary

The subject deals with theoretical principles of technologies for high-purity materials, for example ion exchange, distillation, electrolysis, vacuum extraction, directional crystallization, zone melting. Lessons include preparation methods of bulk semiconductor materials, single crystals and thin layers using CVD or PVD technologies. Materials prepared through these technologies fall into hi-tech materials group applied in electrotechnics, electronics, medicine, aircraft, spacecraft, nuclear and automotive industry.
