Mica Powder
Wanzhu Mining — Mica Powder Product Introduction
Company Profile
LingShou Wanzhu Mineral Products Co., Ltd. owns independent mica mines and complete deep processing production lines. We specialize in mining, sorting, water washing, impurity removal and grading of natural mica. Our full-series products include muscovite powder, phlogopite powder and sericite powder. Multiple iron removal and purification processes are adopted during production to guarantee intact flake structure, stable physical and chemical indicators. Widely applied in insulation, refractory, friction brake, coating, rubber & plastic, building material and welding electrode industries. Custom size, fineness and purity are available, with stable bulk supply, test reports and formula technical support provided.
Product Classification
Muscovite Powder
The most widely used type with high transparency, outstanding insulation and acid & alkali resistance. Available in coarse grain and superfine powder grades, mainly used for electrical insulation, high-temperature heat insulation and high-performance friction materials.
Phlogopite Powder
Superior heat resistance with golden color, withstands higher temperature than muscovite. Ideal for high-temperature refractory parts, welding electrodes and high-temperature sealing gaskets.
Sericite Powder
Thin scaly texture with strong adhesion and covering power, excellent lubricating filling performance. Mostly processed into superfine powder for coatings, rubber, brake pad fillers and anti-corrosion building materials.
Key Performance Advantages
Excellent heat resistance: Muscovite withstands long-term temperature of 500–800℃; phlogopite reaches 900–1100℃, no decomposition, cracking or deformation under high temperature.
Superior electrical insulation: High resistivity and stable breakdown strength without conductive impurities, perfect substrate for motors, home appliances and electronic components.
Natural layered flake structure brings lubrication and buffering effects, reducing brake noise and stabilizing friction coefficient.
Stable chemical property, resistant to acid, alkali, oxidation and moisture, maintaining stable performance in humid outdoor environments.
Good toughness and elasticity; thin flakes resist cracking under rapid temperature changes.
Strict impurity control with low sand, black spot and iron content; uniform color and particle size for every batch.
Standard Specifications
Granular grades: 10 mesh, 20 mesh, 40 mesh, 60 mesh

Main Application Fields
Electrical insulation: Insulation gaskets for motors, microwave ovens, hair dryers, transformers and electronic parts.
Refractory & heat insulation: Mica boards, thermal pads, furnace lining and fire-proof rolls to extend service life under thermal shock.
Brake friction materials: Functional filler to stabilize friction coefficient, eliminate squeal noise and improve wear resistance.
Coatings & anti-corrosion paints: Enhance UV resistance, anti-cracking, rust prevention, gloss and hiding power of paint film, also used as substrate for pearlescent pigments.
Rubber & plastic filling: Boost tensile strength, dimensional stability and flame retardancy, reduce shrinkage and deformation of plastic pipes and rubber seals.
Other usages: Welding electrode raw material, fire-proof boards, waterproof sealing rolls and ceramic fillers.
Supply Advantages
Direct supply from our own mines, competitive price without middleman markup.
Integrated production line for crushing, washing, air separation, magnetic separation and screening, large capacity for long-term large orders.
Test data attached to each batch, third-party inspection acceptable.
Professional technical team to adjust particle size and purity formula for better finished product performance.
Mature logistics system with on-time delivery to factories across the country.
Summary
Wanzhu Mining supplies full-range mica powder with intact flakes and stable physical & chemical indexes. Relying on self-owned mines and mature processing technology, we serve factories in insulation, refractory, friction, coating and plastic industries with reliable long-term mineral raw materials.
