Basic research on ionic-covalent materials for nuclear

Ionic-covalent (non-metallic) solids play an important role in numerous industrial appliions, due to their unique thermal, electrical, magnetic and optical properties. Refractory materials find appliions at very high temperatures, where metallic materials already melt. Among the extreme environments where such materials are used is the nuclear industry, with impressive diversity of
