Abstract
The energy-band structures and cohesive energies for the compounds TiCxN1-x (x = 0, 0•25, 0•50, 0•75 and 1•0) have been calculated self-consistently by the linear muffin-tin orbital method in the atomic-spheres approximation. It is shown that the influence of disorder in the metalloid sublattice on the density of states is small. The nonlinear behaviour of the cohesive energy against x is examined and the calculated band structures are used to analyse the available experimental data on electromagnetic properties of the compounds.
