摘要

Single crystals of Ca_3TaGa_3Si_2O_(14) (CTGS) were successfully grown from stoichiometric melts by the conventional Czochralski technique. The relative dielectric constants, the piezoelectric strain constants and the elastic compliance constants of CTGS single crystal have been determined by an electric bridge and resonance-antiresonance method. At room temperature, the two piezoelectric strain constants d_(11) and d_(14) are —4.58 x 10~(-12) coulombs per newton (C/N) and 10.43 x 10~(-12) coulombs per newton (C/N), respectively. The velocities of the bulk acoustic wave are also calculated.
