Making Fluorophlogopite Ceramics through Ceramic Processing
Fluorophlogopite ceramics, which possesses very good machinability, high electrical resistance and high dielectric strength, is very difficult to be sintered to fully dense state. It is usually made through glass-ceramics processing. In this paper the effects of particle size distribution and sintering agents on sintering of fluorophlogopite ceramics are investigated. The study concludes that dense fluorophlogopite ceramics can be produced through ceramic processing, including careful synthesis of fluorophlogopite powder as raw material, grinding with attrition mill, and pressureless sintering with the help of plumbum contained boron silicate glass as sintering agent in the temperature range of 1100 to 1200°C.
