DIATOMACEOUS EARTH Usage And Synthesis
Chemical Propertieswhite to off-white powder
Chemical PropertiesAmorphous silica, the noncrystalline form of SiO2, is a transparent to gray, odorless, amorphous powder
UsesCelite (R) 545 AW was used as stationary phase in purification of fagopyritols using preparative chromatography. Celite (R) 545 AW was used as packing material for fractionating procedure and the fractions were analysed using GC-ECD, GC/ECNI-MS 2 and IC-MS/MS.
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.
First aidIf this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. If this chemical has been inhaled, remove from exposure. Transfer promptly to a medical facility.
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.
