Iteratomic reaction potentials in titanium diboride

Characteristic temperatures determined by Ti-Ti, Ti-B, and B-B bonds in TiB2 are evaluated Values for the heat capacity, thermal expansion coefficient, bulk elasticity modulus, Gruneisen coefficient, and also exponents for Mie-Gruneisen, Morse, and Buckingham type potentials, and the critical pressure and volume of PV-diagrams are calculated for these bonds. The corresponding properties of these bonds and boride are noted Indices of the Buckingham potential point to the preferred covalent nature of Ti-Ti, Ti-B and B-B bonds in titanium diboride.
