Abstract
Ab initio calculations of the superconducting properties have been performed for niobium carbide (NbC) at normal pressure and upon a 15 and 30% compression. Factors accounting for the relatively low values of the transition temperature T c in transition metal carbides are considered and the possible ways of increasing this parameter are discussed.
