WebJun 15, 2015 · All Ti-, Zr- and Hf-based carbides and nitrides have a simple NaCl-type crystal structure with two sublattices: a metal atom sublattice and a non-metal atom sublattice. The non-metal atom sublattice can normally accommodate up to 50% of vacancies [2] leading to severe off stoichiometry.
