Abstract :
New piezoelectric Sr3TaGa3Si2O14 (STGS) single crystals were grown using the Czochralski technique. The crystal structure of STGS is isostructural to that of Ca3Ga2Ge4O14, which has the trigonal space group P321 and Z = 1. The lattice parameters were a = 8.293(2) and c = 5.078(2) إ. The final R-factors were R = 0.047 and Rw = 0.046 for 1406 unique reflections. The distribution of each cation was found to be ordered in each site. Some piezoelectric properties of STGS are reported.
