Silica (chemistry of the mineral quartz and silica a synonym): Used for the production of steel and cast iron, aluminum, glass and refractories, ceramics, abrasives, water filtration, which is part of cement, filler in cosmetics, pharmaceutical, paper, insecticides, rubber reinforcing agent - especially for a large responsibility on textiles, anti-caking agent in food, brokerage Mattierungsmittel in paints, thermal insulator. Quartz is an ablative material in the rocket engines, space vehicles, the silica-reinforced plastics fiber.

Unable to perform Translation:invalid textSilicon is an important part of the DX-selling silicon. We are in close contact with our counterparts in Europe and the United States over several years to develop products that customers optimal and better logistics. We offer our customers a quality product stable and controlled amounts of impurities. Our silicone is mainly due to long-term contracts.
