Mica mines are widespread in Asia, Africa, and the Americas, but are rare in Europe. Until the 19th century, mica was very valuable in Europe, and prices fell rapidly as colonists mined mica in Africa and South America. Synthetic mica powder wholesale

Mica block mica has very high insulation, good thermal conductivity, good chemical stability, strong acid, strong alkali and pressure resistance, so it is an important raw material for the manufacture of electrical equipment, so it can also be used as an insulating material in hair dryers. Mica also has birefringence, so it is also an optical instrument material for making polarizers. Mica mining used in the electrical industry must be mica blocks with an effective area greater than 4 square centimeters, without cracks, perforations, and non-mica minerals on the edge should not exceed 3 mm. After the mica is mined, the quality is divided into 4 categories according to the effective area, and the best special category is larger than 65 square centimeters.

The most widely used in industry is muscovite mica, followed by phlogopite mica, which is widely used in chemical industries such as building materials industry, fire protection industry, fire extinguishing agent, welding rod, plastics, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigments, etc.

The main purpose is the most used muscovite mica in industry, followed by phlogopite mica. It is widely used in building materials industry, fire protection industry, fire extinguishing agent, welding rod, plastic, electrical insulation, papermaking, asphalt paper, rubber, pearlescent pigments and other chemical industries. Ultrafine mica powder is used as functional filler for plastics, coatings, paints, rubbers, etc., which can improve its mechanical strength, enhance toughness, adhesion, aging resistance and corrosion resistance. In addition to its extremely high electrical insulation, acid and alkali corrosion resistance, elasticity, toughness and sliding properties, heat and sound insulation, and small thermal expansion coefficient, it is also the first to introduce smooth surface, large diameter-to-thickness ratio, regular shape, attached Features such as strong focus.
