%X Silica is an important structural and functional material, which is widely applied in the fields of aero craft, semiconductor, electronic telecommunication, and optical devices. However, the crystallization of cristobalite at elevated temperature has restricted its further application. In the present paper, current research results on the crystallization behavior of cristobalite in silica with different morphologies (bulk, powder, fiber and gel) and different silica matrix composites and different opinions on the mechanism of the crystallization behavior were reviewed. The mechanism of the crystallization behavior was recognized by the surface crystallization in the paper. In addition, the latest research results on the amorphization of cristobalite were also introduced.
