چکیده انگلیسی
A new relation for predicting volume thermal expansion of alkali halides at high temperatures is derived based on the assumption that the two different diffusional driving force models presented, respectively, by Sharma and Sharma (Indian J. Pure Appl. Phys. 29 (1991) 637) and Singh (J. Phys. Chem. Solids 63 (2002) 1935) are equivalent. The input parameters needed for the calculation are the volume thermal expansion coefficient and the isothermal Anderson-Gruneisen parameter, both at room temperature and zero pressure, which are available from the literature. The tests on NaCl and KCl crystals demonstrate that the agreement between the calculated results obtained by this relation and the corresponding experimental data is very good. The applicability of the relation as well as some thermodynamic relationships included in its derivation is discussed.
