Phlogopite Mica Powder

Phlogopite mica powder is a natural mica mineral powder produced from selected phlogopite ore through crushing, grinding, screening, classification, and quality inspection. Phlogopite is a magnesium-rich mica mineral and is often recognized by its golden, yellow-brown, bronze, or brownish color. Because of its special mineral composition and layered crystal structure, phlogopite mica powder provides excellent heat resistance, electrical insulation, flexibility, chemical stability, and reinforcement performance in many industrial systems.

Compared with muscovite mica, phlogopite generally has better high-temperature resistance and is widely used in applications where thermal stability is important. It can maintain good physical properties under elevated temperatures and is suitable for heat-resistant coatings, welding electrodes, insulation boards, refractory materials, rubber products, plastics, and composite materials. Its natural flake structure also helps improve barrier properties, dimensional stability, surface smoothness, and mechanical reinforcement.

WANCHENG MINERAL supplies phlogopite mica powder for global industrial customers who require stable quality, reliable particle size control, and professional export service. Our phlogopite mica powder can be supplied in different mesh sizes according to customer requirements. The product can be used as a functional mineral filler, reinforcing material, insulating additive, heat-resistant filler, and decorative mineral component.

For B2B buyers, selecting the right phlogopite mica powder is not only about price. Particle size, color, purity, moisture, heat resistance, compatibility with resin or coating systems, packaging condition, and export stability are all important factors. WANCHENG MINERAL focuses on consistent production and practical application support to help customers choose suitable mica grades for their formulations.

    Technical Specifications

    Phlogopite mica powder can be supplied in a wide range of particle sizes, from coarse powder to fine powder. Different particle sizes are suitable for different applications. Coarser grades are often used in welding materials, refractory products, construction materials, and surface texture applications. Finer grades are suitable for coatings, plastics, rubber, adhesives, and functional filler systems where better dispersion and smoother surface performance are required. 

    The color of phlogopite mica powder usually ranges from golden yellow to brownish gold depending on the ore source and processing method. Because it is a natural mineral product, slight color variation may occur between production batches. WANCHENG MINERAL can provide samples and batch information for customer evaluation before bulk orders. 

    The technical data listed in this page are typical reference values. Final specifications can be adjusted according to customer requirements, application needs, and actual production batches.
