Abstract: The elastic properties of intermetallic compounds MgB2, TiB2 and LiBC under high pressure and high temperature using the Hama-Suito theory of equation of state based on the augmented plane wave (APW) and quantum statistical methods have been studied. The results have been obtained for P-V-T relationship and isothermal bulk modulus at high temperature up to 1000K and down to compression of 50% (V/V0 = 0.50). The input parameters used in calculation are based on the first-principles method. The importance of extreme compression behaviour has been discussed in terms of the Thomas-Fermi model.
