Magnesium chromate is a chemical compound, with the formula MgCrO4. It is a yellow, odorless, water-soluble solid with several important industrial uses. This chromate can be manufactured as a powder.
Before 1940, the literature about magnesium chromate and its hydrates was sparse, but studies starting in that year looked at its properties and solubility.[1]
As a hydrate, it is useful as a corrosion inhibitor and pigment,[4] or as an ingredient in cosmetics.[5] In 2011, an undecahydrate (containing 11 molecules of water) of this compound was discovered by scientists at the University College London.[6]
Hazards
Magnesium chromate hydrate should be stored at room temperature, and there is no current therapeutic use.[7] It is a confirmed carcinogen, and can cause acute and dermititis, and possibly kidney and liver damage if inhaled, so it should be treated as a hazardous waste.[8]
