Abstract: Research progress in the ceramization of silicone-based polymer was reviewed. Three kinds of ceramic formulas and ceramic effects such as wollastonite, mica, and additives/mica systems were introduced. Wollastonite was satisfactory in enhancing mechanical properties of the hybrid systems. When used as cable threath, mica system quite met the requirements in electrical and mechanical performance. Mixture of mica and inorganic filler could improve the strength of the ceramization products, the presence of inorganic filler improved the compactness of the products. The application and future direction of ceramic systems were also put forward.

Key words: silicone, polymer, ceramic system, wollastonite, mica
