High quality piezoelectric single crystals Sr3TaGa3Si2O14 were grown using the conventional Czochralski method along the Y-axis. The mass density was found to be 5.121?g?cm?3 by the Archimedes method. The relative dielectric constants, piezoelectric strain coefficients and elastic compliance constants of Sr3TaGa3Si2O14 single crystals were determined by an electric bridge and the resonant?antiresonant method at room temperature. The results were , , d11 = ?4.90?pC?N?1, d14 = 3.20?pC?N?1; ; ; ; ; ; and , respectively. The temperature dependent behaviour of elastic compliance constants was also investigated, where zero temperature compensated cuts were not found in the range from ?40 to 120??C.
