In the present communication, a new relationship for the temperature dependences of elastic constants are developed using a new expression for the temperature dependence of bulk modulus and the formulation derived from Tallon's model. The proposed relationship is applied to study elastic constants of NaCl, KCl, CaF_2, MgO, CaO, and Mg_2SiO_4. The result obtained for second-order elastic constants are found to compare well with the experimental data.
