Фаза переходит при этом в раствор, а смесь фаз TiC(V) и TiC остаетс в осадке. Раствор отдел ютTo isolate carbides of the type washed out from the electrolyte and solid solution, the mixture of carbides is placed in a flask, poured 100 cm of sulfuric acid, diluted 1:20, and boiled for 2 hours, maintaining a constant volume. The phase then goes into solution, and the mixture of the phases TiC (V) and TiC remains in the precipitate. The solution is separated.
