Abstract

In this paper, the elastic, piezoelectric, and dielectric constants of Ca₃TaGa₃Si₂O₁₄ (CTGS) single crystals were fully characterized from room temperature to 800°C according to IEEE standard methods. The sensitivity and stability of the temperature sensors based on CTGS crystals were also investigated. One of the elastic stiffness constants-c₁₁^E shows the highest temperature sensitivity. The results of the repeated measurements of X-cut square-plate resonator sample indicate its excellent stability through the entire measurement temperature range.
