The result of growth of RbBe2 BO 3 F2 (RBBF)crystal by hydrothermal method has been reported in this article.RBBF moncrystal of a c-axis thickness up to 5mm has been grown out under a gowth temperature of 400~500℃ and a temperature difference of 10~30℃,using broken RBBF crystal material grown by molten salt method as compost and Rb2 CO 3 and RbF as mineralizer solution.The morphology of RBBF crystal grown by hydrothermal method is discribed through hydrothermal growth process,the conditions for the hydrothermal growth of RBBF monocrystal have been analysed and the formation mechanism of the surface micromorphology such as the growth ladder of (0001)face and growth pits has been studied.
