Molecular formula: SiO2 · NH2O
Properties: Also called the photo white carbon black. More than 99.8% of white amorphous silica content high dispersed micro powder. Particle size in 8 ~ 15 nm, the surface area of 200 ~ 380 m2 / g. With high dispersion performance. Soluble in caustic potash (sodium) and hydrofluoric acid. Insoluble in water and other acids. Absorb the moisture in air form the fine aggregate. The chemical stability. Resistance to high temperature. Don't burn. High electric insulation. High purity (above 99.5%). With high thickening and thixotropic effect. The characteristic of adsorption and reinforcement. By refining of silicon tetrachloride in hydrogen combustion flame heating and hydrolysis, the water vapor in the silicon dioxide generated, via condensation, recycling, acid, ammonia containing air purge system. Used for plastic and coating and thickener and thixotropic agent, the silicone rubber reinforcing agent, plastic film opening agent, powder anti-caking agent, pharmaceutical excipients, cosmetics quality improver, sealing materials, electrical insulation, thermal insulation, printing ink, etc. |
