Uses and synthesis of silicone dioxide powder

silicone dioxide powder is a siliceous rock, silicone dioxide Raw Materials The chemical composition is dominated by SiO2, which can be expressed as SiO2-nH2O, and the mineral composition is opal and its variants.

silicone dioxide CAS 61790-53-2 is a fossilised deposit of diatomaceous earth formed after the death of unicellular plants called diatoms over a period of accumulation of about 10,000 to 20,000 years.

Applications / Functions of silicone dioxide powder

1. silicone dioxide powder is mainly used as thermal insulation material, chemical filler and catalyst carrier.
2. silicone dioxide CAS 61790-53-2 is used as filtering agent for synthetic resin, chemical fibre, dyestuff, paint, solvent, acid, electrolyte, glycerol, etc. It is also used as carrier for fertilizer and pesticide, as ideal filler for plastic, rubber and pesticide, as filtering aid for recovery of sodium thiocyanate, as activated carbon for decolouring of nylon solution, and as anticaking agent for ammonium nitrate pellet.
3. It is also widely used in light industry, food, medicine, building materials, petroleum, papermaking, environmental protection and other sectors. silicone dioxide Raw Materials has a broad development prospect.
4. silicone dioxide powder is used in diatomaceous earth ore treatment selection.

Physicochemical Property of silicone dioxide powder

silicone dioxide CAS 61790-53-2 The colour is white, off-white, grey, light grey, light grey-brown, light yellow and so on.

High chemical stability, insoluble in hydrochloric acid, soluble in alkali, relatively incompressible, soft, sound insulation, wear-resistant, heat-resistant and many other excellent properties.

Production methodprocess of silicone dioxide powder

All of them are open pit mining, most of the mines use the soil method, a few mines have reached the level of semi-mechanisation. The beneficiation method generally adopts gravity beneficiation
