Characterization and temperature sensor application of Ca3TaGa3Si2O14 crystals

摘要

In this paper, the elastic, piezoelectric, and dielectric constants of CaTaGaSiO (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-c 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.
