mica, muscovite

الوصف

Mica is a crystalling mineral which can provide excellent electrical properties, heat resistance, and physical-chemical properties. Muscovite mica, phlogopite mica and fluorophlogopite mica(synthetic mica) can be regarded as the one of the most important insulating materials for the current electric industry. Muscovite mica KAL2ALSi3O*0(OH)2 and Phlogopite mica KMg3ALSi 3O*0(OH)2 are natural minerals. The crystal structure of natural mica contains(OH-),which begin to decompose at **0C or **0C).The thermal gravimetic loss of natural mica increases suddenly and starts to decrease at **0C(or **0C). Fluorophlogopite FMg3ALSi3O*0F2 is a non-natural synthetic mica crystal. Because the (OH) does not exist in the crystal structure of Fluorophlogopite, thus Fluorophlogopite can be decomposed even not reaching the melting point(***0C). Fluorophlogopite provides the highest resistant ability among all mica types.
