Analysis
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 KAL2ALSi3O10(OH)2 and Phlogopite mica KMg3ALSi 3O10(OH)2 are natural minerals. The crystal structure of natural mica contains(OH-),which begin to decompose at 500C or 650C).The thermal gravimetic loss of natural mica increases suddenly and starts to decrease at 650C(or 850C). Fluorophlogopite FMg3ALSi3O10F2 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(1350C). Fluorophlogopite provides the highest resistant ability among all mica types.
