Black Mica is stratiform mineral ,Its composed of potassium (K), aluminum (AI), magnesium (Mg), Iron(Fe) and lithium(Li). There are
Black Micadifferent categories of mica, including white mica, phlogopite, biotite and lepidolite (Lithia mica) . white mica is widely used in industry and national defense because it is elasticity, tenacity and insulativity. it is also acid and alkali resistant, and corrosionproof, which can be stripped, with low coefficient of expansion etc.

The Jinli Minerals have successfully developed another category of mica powder, which is smooth on the surface of flakes, thick in layer, regular in shape with strong adhesion and slipperiness, widely used in many Chinese and foreign prestigious enterprises.

The Main Use and Functions:

Black Mica powder can be used in paint and coating to reduce the damage of ultraviolet rays or other Light and heat damage to the paint film, promote coating acid and alkali. and insulation, and to t= strengthen its durability ,freezing resistance corrosion resistance, water resistance etc. it helps to strengthen the adherence to the layer, improve its intensity, brightness, tenacity and Compaction. As a result ,it is conducive to reduce the ventilation ,to prevent speckle and chaps as well as reduce sediment in the paint. As a prior filler in paint, mica powder can be used to substitutesome expensive raw materials in the paint so as to reduce the productioncost.

1) Black Mica powder is also the basic raw material for mica ceramicsproducts.
2) Black Mica powder can be applied in protecting layer of welding rods, conducting wires and electric cables.
3) It can be use as suspended substance in fire-fighting dry powder.4) It can be taken as a filler , a shelter, a lubricating substance, a drawing of patterns in plastics, rubber, asbestos products and sealing materials.
5) It can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid and alkaliproducts.
6) It can be used as coating in models of Cast metal, the brightening material in aluminum and paint in Plating bath.
