Abstract :
Second order elastic constant temperature dependences of different quality quartz crystals were studied. The simplified phenomenological theory was applied to calculate second order elastic constant temperature dependences. The bulk acoustic waves propagation under the bias of temperature field or of the uniaxial mechanical pressure was considered. It was found that crystal quality changes have caused certain variations of some third order elastic constant values and some temperature coefficients
