silica powder / quartz powder
MOQ 28 Ton · Seller will confirm final rate
Silica Powder (Quartz Powder) is an ultra-pure crystalline silicon dioxide mineral produced by fine grinding and air-classifying washed quartz lumps. Characterized by high chemical purity, high hardness (7 on Mohs scale), extreme thermal stability, and low thermal expansion, it is highly inert to chemical attack. It is widely applied as a structural filler, refractory base, and raw material in high-performance manufacturing. Key Characteristics & Applications: Paint & Protective Coatings: Provides chemical resistance, scratch hardness, weatherability, and corrosion resistance in heavy-duty epoxy and industrial coatings. Glass & Ceramics: Primary raw material for high-clarity glass, vitreous ceramic bodies, glaze formulations, and sanitaryware. Refractories & Foundries: High melting point (~1713°C) makes it ideal for thermal insulation refractories, foundry mold washes, and investment casting. Construction & Polymers: Used in epoxy flooring, quartz stone countertops, artificial marble, adhesives, and specialty mortars. Technical & Commercial Specifications: Form: Fine Powder Chemical Purity: Min 98.5% – 99.5% Color: Pure White / Off-White Hardness: 7.0 Mohs Mesh Size / Particle Size: 100 Mesh/ 200 Mesh / 300 Mesh / 400 Mesh / 500 Mesh Moisture Content: Max 0.5% Packaging: 25 kg / 50 kg HDPE bags or 1000 kg Jumbo Bags
