Fused silicon dioxide

White carbon black is a highly-refined chemical product mainly composed of SiO2 (approximately *0%**5%). It is white in color; its name is due to the fact that its main properties and uses are similar to those of carbon black. Its chemical characteristics are stable, it has good dispersion, and it is insoluble in water, heat resistant, nonflammable, resistant to acids and alkalis, non-polluting, porous, and a very good insulator. White carbon black is chiefly used as a rubber filler and reinforcing agent. It is used in the manufacture of white, colored, and transparent rubber products. It can significantly improve the tensile strength, tear resistance, and abrasion resistance of rubber products.

White carbon black can produce light colors and transparency in rubber products. And since it is non-toxic and tasteless, white carbon black can be widely used in plastics, paints, inks, paper, pharmaceuticals, everyday chemical products, and foods. It currently possesses nearly boundless development potential. White carbon black can be synthesized from silicon-rich non-metallic minerals such as kaolin, wollastonite, serpentine, bentonite, and diatomaceous earth. Industrial white carbon black consists of amorphous silicon dioxide precipitated using chemical methods. This simple-to-use additive material can ensure easily controlled product quality. White carbon black is inexpensive and highly effective. It is a high added value product made by processing non-metallic minerals. It can be produced by precipitation from a sulfuric acid solution of silicates, or made using a vapor phase method.
