Abstract: Machinable fluormica glass-ceramics are a new type of structural materials. The materials have been a focal point in the field of ceramic researches since being developed because these materials can be machined by conventional metallic tools. The major crystalline phases in the traditional fluormica glass-ceramics are fluorphlogopite and tetrasilicic fluormica. In this paper, the recent advances at home and abroad in the researches of barium-mica, calcium-mica, lithium-mica glass-ceramics and multiple phase fluormica glass-ceramics are reviewed.

Key words: barium-mica%calcium-mica%lithium-mica%multiple phase fluormica glass-ceramics
