Enige ternaire chalcogendien van chroom vanadium, niobium en tantaal

This thesis describes the investigation of some ternary sulphides and selenides of the transition metals chromium, vanadium, niobium and tantalum. The compounds investigated contain either a monovalent metal (Li, Na, K, Cu, Ag) or a large divalent metal (Sr, Ba, Pb, Eu) in addition to the transition metal. Most of the compounds had not been prepared previously..
