Natural Crystal Structure for Unique Performance
Natural Silica Powder keeps the natural crystal structure of quartz ore. We make it only through physical crushing, grading, and purification. We do not melt it. This keeps the high hardness, low thermal expansion, and excellent dielectric properties of quartz. These natural traits give it an advantage in many applications. Our factory is located at the foot of Mount Huangshan. This region has rich, high-quality quartz resources. This gives us a stable and high-grade supply for product.
Full Range of Sizes for Many Industries
Our production uses mechanical crushing and fine grading. We also add acid washing to remove impurities. This ensures the SiO₂ content stays above 99%. Our Natural Silica Powder covers a complete range from 300 mesh to 2000 mesh. Our annual capacity is 20,000 tons. We can meet the needs of many industries at the same time. Over the last 25 years, our product has served hundreds of customers around the world. Our stable quality and reliable delivery have earned us a strong market reputation.

Broad Applications and Custom Service
Natural Silica Powder serves many industrial sectors. In electronics, it fills epoxy molding compounds and potting compounds. Its insulation and low dielectric constant keep electronic parts safe. In electrical products, it is an insulating filler for high-voltage switches and transformers. In coatings and plastics, it gives higher hardness and weather resistance. In ceramics, refractories, and abrasives, our Natural Silica Powder is also very useful. We accept orders for any size from 300 mesh to 2000 mesh. Just tell us your target size and purity needs. The minimum order is 1 ton.
