The polycrystalline materials of SrWO4 were synthesized by means of a solid phase reaction with analytical purity SrCO3 and WO3 at high temperature.The transparent SrWO4 single crystal with dimension of Φ 22 mm×40 mm has been successfully grown along a-axis by Czochralski method.X-ray powder diffraction results show that the as-grown SrWO4 single crystal belongs to tetragonal system and I41/a space group.The measured density of segregation coefficients of W and Sr elements in SrWO4 single crystal are close to 1 by the X-ray fluorescence method.
