Lattice parameter of the non-stoichiometric compound TiN_x

Contamination-free TiN_x was prepared and the lattice parameter (a₀)–nitrogen content (x) relation determined. The result can be expressed as a₀ = 4.1925 + 0.0467_x (in Å) in the range 0.605 ≤ x ≤ 0.999. Density measurement showed that no titanium vacancies existed in the lattice.
