Summary
Noble metals, or so called „precious metals“, comprise silver, gold and metals from the platinum group, which find extensive use in electrical engineering and micro- electronics. This concerns primarily electrical conductivity and constant quality of metal surface (Au). Refractory metals, such as W, Mo, Ta, Nb and others, are interesting for the area of vacuum technology. In the group of functional materials (magnetic materials, luminescent materials, etc.). some rare metals find their use. Students will acquire information on production of these metals, influence of admixtures on their properties, possibilities of their modifications and application in practice.
