Abstract : The following topics are discussed: (1) localized versus collective behavior of d-electrons in transition metal oxide systems having the perovskite structure, (2) semiconductor-metal transitions in pure and vanadium doped niobium dioxide, (3) structural aspects of the metal-insulator transitions in chromium and niobium doped vanadium dioxide, (4) pressure effects on the semiconductor - semimetal transition in titanium sesquioxide and (5) the effect of structure on the heats of formation of solid solutions of cesium chloride with other alkali halides.
