“…Changes in the stoichiometry of ternary Hf x Ta y C z compounds are probable because of a wide area of homogeneity of the cubic carbide phases in the HfTaC system: HfC and TaC have the same NaCl-type crystal structure and can form infinite HfTaC solid solutions in the whole range of compositions. [23] The obtained values of the lattice constant a show that the plasma dynamic synthesis makes it possible to produce not only the well-known HfC, TaC, and HfTaC 2 compounds, but also specific and hypothetical Hf 9 TaC 10 , Hf 7 TaC 8 , Hf 6 TaC 6 , Hf 3 TaC 4 , Hf 4 Ta 3 C 6 , HfTa 2 C 3 , and HfTa 7 C 8 having a cubic structure. Hf 7 TaC 6 , Hf 4 Ta 3 C 6 , HfTa 2 C 3 , and HfTa 7 C 8 were predicted for the first time, while other compounds have recently been computationally predicted.…”
