  In this study, we found a possible method to reduce the anisotropy of the thermal stress generated on langasite-type La3Ta0.5Ga5.5O14 (LTG) piezoelectric crystals arising from the mismatch of the thermal expansion coefficients and Young’s moduli of the crystals and metals at high temperatures. We attempted to replace La3+ in LTG by a larger ion and considered Sr2+. Single crystals of strontium-substituted LTG (Sr-LTG) were grown using the Czochralski method. The anisotropic thermal stress was reduced effectively.
  We also clarified a relationship between piezoelectric property and crystal structure in melilite-type crystals. Based on this knowledge, strontium-substituted calcium magnesium silicate Ca2MgSi2O7 (Sr-CMS) single crystals have been grown. The Sr-CMS crystal has piezoelectric d’31 constant 2.1 pC/N and its compressive strength 830 MPa.
  Both the Sr-LTG and the CSMS30 single crystal is a superior candidate material for pressure sensors at high operating temperatures.
