The dielectric, piezoelectric and some elastic constants of the Ca3NbGa3Si2O14 crystal had been determined by using Ycut and (yxl)30°cut crystal samples.The calculated piezoelectric constants as functions of cut a ngle of (yxl)θ cut were also given. The Ca3NbGa3Si2O14 crystal showed superior piezoelectric properties with relatively large piezoelectric constants (d11=7.93×10-12C/Nd14=-5.88×10-12 C/N) compared with La3Ga5SiO14 crystal.
