Talc porcelain is made of mineral talc (3mgo.4sio2.h2o) as the main raw material, with appropriate amount of clay and BaTi03 and other ingredients added to it through mixing, grinding, molding and high-temperature sintering processes.The main crystal phase of talc porcelain is original enstatite, namely magnesium metasilicate (chemical formula is Mgsio3). It is a kind of high-frequency structural ceramics with excellent electrical properties and low price, which is often used as insulation parts in high-frequency equipment.
