title: Temperature coefficients of elastic constants of trigonal, hexagonal, and tetragonal crystals.
abstract: Temperature coefficients of elastic constants (TC(IJ)) for trigonal, hexagonal, and tetragonal crystals have been obtained. The TC(IJ) of several trigonal, hexagonal, and tetragonal crystals have been calculated and compared with known experimental data. The nature of the anomalous TC66 of quartz has been discussed in detail.
