Abstract
A new piezoelectric Ca3NbGa3Si2O14 (CNGS) single crystal was synthesized by a solid state reaction and grown using the Czochralski technique. The crystal structure of the CNGS; was found to be isostructural with La3Ga5SiO14 (LGS). The unit cell parameters were a=0.087 nm and c=0.4989 mu and the space group was P321. The distribution of each cation was found to be ordered in each site. Some piezoelectric properties of CNGS are given.

Keywords: Ca3NbGa3Si2O14, Czochralski, Structure, Piezoelectric.
