Star Mica Powder introduced:
(1) White Mica Powder is a non-metallic minerals, contains a variety of elements, the main ones being SiO 2, in general the 49% Al 2 O 3 content of about 30%. Mica has good flexibility and toughness. Insulation, high temperatures Acid and Basic Resistance, corrosion resistance, adhesion, and other characteristics, is an excellent additive. It widely used in electrical equipment, welding electrodes, rubber, plastics, paper, paint, coatings, paints, ceramics, cosmetics, new building materials industries, uses extremely broad. With the continuous development of science and technology, people open up new application areas.
(2) the characteristics and white Mica Powder main chemical components
Muscovite Crystal was 6 of tabular and columnar square, adjoining plane-state, aggregates Commissioner, or in a film-like scales, so that debris muscovite. Debris was white transparent translucent Muscovite state, and the texture and pure, without spots. Flake mica ore in the film for 2-10 mm diameter, Molecular Formula for KAl2 (AlSi 3 O 10) (OHF) 2. Its chemical composition shown in the table below: muscovite the main chemical in:

The main purpose muscovite：
White Mica Powder is the characteristics of insulation, high temperatures, luster, and material properties of chemical stability, good at good insulation, flexibility and toughness. There are processed into Mica Powder sliding of better coverage and strong adhesion.
（A）Daily chemicals: mainly used for cosmetics, Carmine and pearl pigment and other light. Increase luster.
（B）Mica ceramic raw materials: Mica ceramics can be used as additives, scalability and high temperature insulation properties.
（C）Paint Tim material: Pearlescent paint using mica do tim expected, will enhance the transparency and gloss paint, and reduce costs.
（D）Tim plastics and rubber materials: plastic and rubber after adding Mica Powder plastic and rubber can enhance the aging resistance, increase strength, reduce production costs.
（E）Building materials: Mica Powder used in the more extensive construction materials, such as roofing materials used in a waterproof, fire prevention, insulation, and insulation and decorative role. For asphalt felt, plumbing, mortar and cement agent can improve performance, and so on.
