Silica Powder
Application：
As a non-metal stone, quartzite has wide applications. Normal quartzite contains 90-99% of silicon dioxide. It is applied to industries such as super class glass (e.g. float glass, sun-e glass, tec glass and low-e glass), refining, fire-resistant material, plastics, ferroalloy, crystal silicon, white carbon black, chemical fibre and ceramic enamel. Purity degree of silicon dioxide contained in refine quartzite is 99-99.5%. It is applied to make those high-tech and high profit products like painting, plastics, high voltage ceramics, grinding, solid lubricant, rubber, medicine, cosmetics, food, precise casting, insulation materials and kinescope, etc.
Trait：
Produced through chemical blanching and the superfine processing from the high quality powder quartz and the quartzite
High pure white color, good gloss, anti-corrosive, anti- acid and anti –alkali. With unique degree of hardness and the low relative surface, it is good at increasing rigidity and the resistance of product
With good insulating property, be suitable for application in the high insulation aspect mainly used in glass fiber silicon powder
