We have successfully grown high quality piezoelectric single crystal of Sr3NbGa3Si2O14 (SNGS) by the Czochralski technique. Transparent and pale yellow boules of approximately 60 mm in length and 16-18 mm in diameter were obtained. A full set of material parameters including dielectric, elastic and piezoelectric constants of SNGS crystal were measured in a temperature range from 220 K to 310 K Components of the thermal expansion tensor were also determined.
