Abstract

A3NbGa3Si2O14 (A=Sr, Ca) compounds were grown using the Czochralski method after preparing by solid-state reaction. X-ray structure analysis of grown Sr3NbGa3Si2O14 (SNGS) and Ca3NbGa3Si2O14 (CNGS) single crystals showed that they were isostructural to that of Ca3Ga2Ge4O14, which had space group P321. The lattice constants of SNGS and CNGS were calculated to be a=8.282, 8.087 and c=5.073, 4.980 Å, respectively. The final R and Rw values for the refinement were 0.0353 and 0.0354, respectively. Piezoelectric properties of these crystals were measured.
