Thermodynamic Properties of Titanium Carbide of Variable Composition at High Temperatures
Values of the enthalpy of titanium carbide specimens of four different compositions in the homogeneity range have been determined experimentally in the temperature range 1300–2500°K. Equations have been derived for the temperature dependence of the enthalpy, specific heat, and change in entropy of the four carbides. It is concluded that the more rapid increase in enthalpy that occurs in some nonstoichiometric carbides is due to the formation of thermal vacancies.
