The solid phases of the different time were identified by means of chemical analysis, XRD, FT IR, SEM. The results show that the solid phases are spherical and sheet szaibelyite, which is different from those of non hydrothermal condition. On these grounds we suggested the crystallization mechanism of szaibelyite under the hydrothermal condition and then discussed the effects of hydrothermal properties on the crystallization mechanism.展开更多
