Specific Heat of TiB2

Several thermal properties are important to most applications of ceramics at high temperatures. The first of these is the specific heat, i.e., the amount of energy absorbed per unit mass to increase the temperature of the material by 1 K. For specimens with relatively high purity and density, this quantity is insensitive to grain size variations or the presence of small amounts of impurities. The specific heat of TiB2 increases monotonically with increasing temperature. The rapid rise at low temperature and the linear variation at high temperature is readily fit by an interpolation formula of the form Cp = c0 + c1(T/K − 273) + c2exp[−c3(T/K − 273)], where Cp is the specific heat at constant pressure, and the parameters are c0=976J/(kg K), c1=0.21J/(kg K), c2=−426J/(kg K), and c3=0.008 for 293K⩽T⩽2273K. The relative standard uncertainty of the specific heat when these parameters are used is 1.5 % when the uncertainty estimate is based on the standard deviation of the fit. Is the specific heat at constant volume CV, which may be calculated from the thermodynamic relation CP−CV=Tρ−1Bα2V, where αV is the mean volumetric coefficient of thermal expansion (CTE)? For isotropic materials, αV = 3 αm, where αm is the mean linear CTE.
