Hot Sale Phlogopite Bronze Mica For Refractory Materials

Phlogopite, also called bronze mica, is commonly in yellowish-brown or reddish-brown colors with vitreous luster,  some in greyish-green color. Its cleavage plane has nacreous luster or submetallic luster. Phlogopite is pseudo-hexagonal crystalline or short cylindrical model. Phlogopite has excellent dielectric properties, such as relatively high insulating strength and large electrical resistance, low electrolyte loss, good arc-resistance and corona resistance. As to its excellent tenacity, high mechanical strength, resistance to high temperature and dramatic temperature changes and acid and alkali, phlogopite is widely used in  heat-resistant insulating materials, heavy-duty anti-corrosive coatings, fireproof coatings and refractory materials, and aviation & radio industry.

There are two manufacturing processes of mica powder: dry grinding and wet grinding. We have our own factories to produce these two products. Dry ground mica powder is produced by physical grinding without changing any natural property of mica. We adopt total enclosed filling system to guarantee quality during the whole production process. In the screening process,we also employs proprietary equipment and technology to ensure uniform particle distribution and stable quality. As to its superior performance, dry ground Muscovite has been extensively used in production of various products, including fiber cement construction panels / wallboards, plastics, rubber, paint, coating, welding electrodes, oil drilling and brake pads. ● Dry ground process

Wet ground mica powder is produced from natural mica flakes through a series of processes, including cleaning, washing, purification, wet grinding, drying, screening and grading. The unique production process retains the sheet structure of mica , therefore wet ground mica is featured by large radius-thickness ratio, low sand and iron content, high purity, whiteness and glossiness. The unique property of wet ground mica makes it widely used in industries such as paint, coating production, rubber, plastics and ceramics. It is especially effective to improve product's electrical strength, rigidity, heat resistance and to reduce molding shrinkage and cost. ● Wet ground process
