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.
