Silicon Dioxide raw Materials powder Silicon Dioxide
Product Overview:
Silicon dioxide is a compound containing only two elements, oxygen and silicon, with the chemical formula SiO2, commonly known as silica, and is the most common and stable compound of silicon. It is widely distributed in nature and constitutes a variety of minerals and rocks. Silica exists in both crystalline and amorphous states, the most important of the crystalline silica being quartz. Pure quartz is colourless, and the common sand is silica mixed with impurities.

Silicon Dioxide powder Usage and Synthesis.
About 70% of silica is used as reinforcing filler for natural rubber and synthetic rubber, and the rest is used as filler for synthetic resin, ink thickener, pigment antiprecipitant in paint, matting agent, soft polishing agent for vehicle and metal, and antisettling agent in emulsifier.
It can also be used as pesticide carrier and filler for lightweight newsprint. Due to the advantages of good electrical insulation, low heat generation, light colour and non-pollution of products, silica is also widely used in hoses, tapes, heat-resistant gaskets, rubber rollers and medical products.
Uses of Silicon Dioxide.
Silicon dioxide is the main raw material for the manufacture of glass. Silicon dioxide is the main raw material for the manufacture of glass. The glass made from only one raw material is called quartz glass, which has the characteristics of high temperature resistance and ultraviolet transmission. Silicon dioxide is also an important raw material for the manufacture of optical fibres.
A large number of silicon dioxide used as a rubber reinforcing agent, to prevent the plastic film adhesion of the opening agent, pigment anti-settling agent, paint matting agent, viscosity regulator, pharmaceutical excipients, catalyst carriers and used in cosmetics and so on.
It is used as filler for colour TV cable, wire casing and rubber transparent base. It is also used as thickener, thixotropic agent, anti-settling agent, matting agent, plastic opening agent, liquid drug adsorbent, cosmetic and papermaking filler.
Preparation method of Silicon Dioxide.
Product Methods of Silicon Dioxide.
Combustion method will be purified silicon tetrachloride, hydrogen and air of a uniform mixture of gas sent to the combustion chamber, in 1000: or so due to hydrogen combustion in the air produced by water so that the high temperature hydrolysis of silicon tetrachloride and the generation of silicon dioxide, the combustion gas containing aerosolized silicon dioxide is sent to the condensation chamber, silicon dioxide condensation into particles, separated by the cyclone separator, the exhaust gas is discharged by the washing of the silicon dioxide obtained by the ammonia or dry air The fumed silica is produced by ammonia or dry air deacidification. Its SiCl4 + 2H2 + O2 [combustion] → SiO2 + 4HCl
