摘要: Abstract In this paper, polycrystalline materials of BaWO 4 were synthesized by solid-state phase method, and a single crystal was successfully grown along c -axis direction using the Czochralski method. Up to 20×22×80 mm 3 obtained, X-ray powder diffraction results show that as-grown belongs scheelite structure. The effective segregation coefficients Ba W measured fluorescence near 1. rocking curve from (2 0 0) plane on High-resolution diffractometer D5005, full-width at half-maximum value found be 26.64′′ density hardness measured, in agreement with calculated result, Mohs about 4.
