[Raw material synthesis and characterization of YVO4 birefringent crystal]

In this paper, synthesis of YOV4 birefringence crystal raw material in liquid phase was studied. Mostly, the effects of solution's pH values and some other synthesis conditions on purity and whiteness were discussed. Infra-red spectrometry, X-ray powder diffraction and UV spectrometry were used in the characterization of the raw material and single crystal, and in this way the best method of synthesis was defined. The result of the study indicates that the purity of the raw material had decisive effect on the crystal growth. Flawless crystal with the dimensions of phi 40 x 40 x 50 mm3 was grown by Czochralski (CZ) technique.
