Abstract
The possibility of the synthesis of hydrogen-nonstoichiometric cubic titanium carbide ТiС х of high purity from powdery nonstoichiometric cubic titanium carbohydride ТiС х H y or nonstoichiometric titanium carbide with admixture hydrogen by annealing in a continuously maintained vacuum of no worse than 1.33 × 10–3 Pa at temperatures of 600–750°C for several hours has been shown. Similar annealing at higher temperatures (T ≥ 800°C) does not lead to the complete removal of hydrogen from a sample due to intensive sintering. In this case, it seems that pores between sintered particles are hydrogen traps, and the release of hydrogen through the surface of sintered particles is hindered.
