PHOSPHATE-BONDED SYNTHETIC MICA CERAMICS.

The present paper covers methods of producing mica ceramics starting from two raw material systems: one system consists of two kinds of fluormica differing in melting point (i. e. , fluorphlogopite and fluortetrasilicic mica); the other system consists of fluorphlogopite and talc). Optimal conditions for particle size and mixing ratio of raw materials, amount of H//3PO//4 to be added, pressing process, forming pressure and firing temperature were determined. Texture of the ceramic obtained was examined and physical properties measured.
