Thermodynamics of niobium chlorides and mixtures with alkali chlorides,al reduction of niobium ions in chloride or chloride + fluoride melts. However the current efficiency during electrolysis is strongly dependent on the “average” valence of the bath. Different reduction steps are proposed with niobium valences ranging from V to I. This is supported by the existence o

High Temperature 93Nb NMR Study of Liquid NbCl5 and its Mixtures with Various Alkali Chlorides, NbCl. quadrupolar relaxation dominates. Both the chemical shift and the relaxation rate exhibit a characteristic temperature dependence indicative of the Nb.Cl. ↔ NbCl. dimer-monomer equilibrium. In (CsCl/NaCl). mixtures a strong increase of the .Nb relaxation rate is observed on melting. This is n

The Synthesis of Borides, Carbides and Silicides of Refractory Metals in Ionic-Electronic Melts,efore the synthesis is performed at elevated temperatures to enhance the mutual diffusion. If any of the components is transferred to the solution by means of transport reactions, the effective contact area is increased many-fold and the synthesis temperature and time are reduced considerably. This,
