Abstract :
Refined data of temperature dependences, elastic, dielectric, piezoelectric and thermal expansion coefficients were received for temperature range -100 to 100°C. Single and double rotated Z temperature cuts were calculated. Q-factor of LGS resonators was measured in temperature range -200 to 100°C
