Magnesium arsenic reduces its corrosion rate in a salt solution by a factor of nearly ten. Research showed that magnesium's tendency to creep at high-temperatures is eliminated by the addition of scandium and gadolinium. Flammability is greatly reduced by a small amount of calcium in the alloy. Magnesium forms a variety of compounds important to industry and biology, including magnesium carbonate, magnesium chloride, magnesium citrate, magnesium hydroxide (milk of magnesia), magnesium oxide, magnesium sulfate, and magnesium sulfate heptahydrate (Epsom salts). Magnesium has three stable isotopes: , and . All are present in significant amounts (see table of isotopes above). About 79%
Magnesium chromate Magnesium chromate Magnesium chromate is a chemical compound, with the formula MgCrO. It is a white or brownish, 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. It is available commercially in a variety of powders, from nanoscale to micron-sized, either as an anhydrous or hydrated form. As a hydrate, it is useful as a corrosion inhibitor and pigment, or as an ingredient in cosmetics. In 2011, an undecahydrate
