Carbothermic reduction of calcium tungstate in the presence of various oxides

The possibility of reduction of calcium tungstate in an inert medium (in vacuum and argon) was investigated. As components involving WO 3 and B 2 O 3 , natural materials—namely, scheelite and datolite concentrates—were used. The main products of reduction are W 2 B 5 , WC, W 5 Si 3 , and SiC. The ap...
