Abstract

In this paper, a kind of fully ordered langasite family crystals Ca 3TaGa3Si2O14 (CTGS) were grown by the Czochralski pulling method and cut into lateral mode. The dielectric, elastic and piezoelectric properties of them were investigated as functions of temperature (up to 1073.15 K) and pressure (up to E-7 torr). It was found that all the crystals exhibited pressure stability properties and temperature dependent characteristics. According to the calculation, the dielectric permittivity, elastic coefficient and piezoelectric coefficient were about 17.66, 9.06 pm2/N and 3.77 pC/N, respectively. The good properties make CTGS promising candidates for sensing applications at high temperature and high vacuum conditions.
