| Abstract: | Theremoelastu properties of non-cubic minerals at high temperature can be understood adequately by knowing the temperature dependences of their elastic constants.It has been found that there exists a precise relationship showing exponential dependence of their elastic constants onisobaric volume expansion for some typical non-cubic minerals such as Al2O3 and Mg2SiO4 at high temperatures.We have calculated the values of elastic constants at different temperatures for the non-cubic minerals under study.The calculated values of elastic constants are found to show fairly good agreement with available experi mental data. |
