Product Details

Product NameFumes, silica
CAS No.69012-64-2
EINECS No.273-761-1
MW0
AppearanceFine white powder with particle sizes generally below 1mm. This is not the same as the commercial products “fumes silica,” “silica gel,” “precipitated silica,” or “fused silica.” It is formed during the electric arc production of elemental silicon from quartz, which is reduced to silicon monoxide, escaping from the furnace and oxidized by air to silicon dioxide. This condenses to form spherical particles. For the production of ferrosilicon, iron metal is added to the charge; during charging there is also exposure to crystalline silica.
density 0.45-0.67[at 20℃]
Water Solubility 135mg/L at 37℃

Fumes, silica Usage And Synthesis

Chemical PropertiesAmorphous silica, the noncrystalline form of SiO2, is a transparent to gray, odorless, amorphous powder
Safety ProfileAn inhalation hazard. Much less toxic than crystalline forms. Does not cause silicosis. See also other silica entries
Potential ExposureAmorphous fumed silica is used as a mineral, natural or synthetic fiber. A potential danger to those involved in the production and handling of fumed silica for paint pigments or catalysts. Diatomaceous earth is used in clarifying liquids, in manufacture of fire brick and heat insulators; used as a filtering agent; as a filler in construction materials; pesticides, paints, and varnishes. A potential danger to those involved in mining of diatomaceous earth or fabrication of products there from.
IncompatibilitiesSilica, amorphous is a noncombustible solid. Generally unreactive chemically. Incompatible with fluorine, oxygen difluoride, chlorine trifluoride. Soluble in molten alkalis and reacts with most metallic oxides at high temperature.
Waste DisposalSanitary landfill.
