In the present communication a relationship between elastic constants and thermal expansivity is disclosed in high temperature region at atmospheric pressure. The relationship is shown for ionic solids viz. NaCl, KCl, CaO and MgO. The analysis is based on the experimental data tabulated by Anderson
In the present study various relationships, belong to the temperature dependence of elastic constants for NaCl at atmospheric pressure, are analyzed. Relationships are modified on the basis of the assumption that the Anderson-Gruneisen parameter remains unchanged with the change in temperature. It i
Thermoelastic behaviour of solids at high temperatures can be understood adequately by knowing the temperature dependences of their elastic moduli. It has been found that there exists a precise relationship showing exponential dependence of elastic moduli on isobaric volume expansion for some typica
