Chlorination of niobium oxides in chloride melts

Melt T(°S) Mass of salt (g) Nb (Wt%) Colour of quenched melt [Pg.249]

From the analysis of all available data we suppose that chlorination of Nb02 and NbO by HCI gas involves [Pg.250]

Based on the experimental results and taking into account the coordination properties of vanadyl ions (niobium s closest analogue) in alkali chlorides [19] we assume that NbOCl4 chloride complexes are formed as intermediates in reactions of NbO and Nb02 with hydrogen chloride. [Pg.250]
