We have grown a new langasite-type piezoelectric single crystal Sr{sub 3}TaGa{sub 3}Si{sub 2}O{sub 14} (STGS) with dimensions of 15 mm in diameter and 30 mm in length by using the Czochralski technique. The X-ray powder diffraction (XRPD) of single crystal was performed at room temperature. The thermal expansion coefficient perpendicular to Z direction has been measured as 3.2x10{sup -6} K{sup -1} between 343.15 and 493.15 K, and along Z-axis, 9.7x10{sup -6} K{sup -1} between 318.15 and 503.15 K. The specific heat of the crystal has been measured as 0.68 J g{sup -1} K{sup -1} at 468.15 K. The transmittance spectra from 200 to 3200 nm annealed in different atmospheres were measured.
