This product is massive quartz made from refined quartz sand through melting at high temperature, quench crushing and grading. It is colorless and transparent and sometimes semi-transparent and foggy.

Mainly used in optical fiber, IC, optical lens, new generation metallurgy-purpose furnace lining, sophisticated ceramics products, medical vessels, special glass and products.

With massive fused quartz as raw material and based on different purposes, various particle sizes of granular fused quartz sand are produced through mechanical machining, magnetic separation, impurity removal and sieving. This product is characteristic of stable chemical properties, good resistance to acid/alkali, heat and wear, low thermal expansion coefficient, high purity, excellent insulation property, extremely low thermal and electrical conductivity and excellent thermal stability.

Used for raw material in refractory material, ceramics and glass, epoxy resin casting, electronic packing compound, electric light source, medical treatment and casting industry.
