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 malate characteristic of having two elemental magnesium molecules, whereas magnesium malate has a single elemental magnesium molecule. Magnesium malate Magnesium malate, the magnesium salt of malic acid, is a mineral supplement often used for nutritional concerns. It is represented by the chemical formula C4H4MgO5 and has a molecular weight of 156.376 g/mol. Magnesium malate is discussed as being a more bioavailable form of magnesium, along with other forms such as citrate and glycinate. Dimagnesium malate is another common form of this compound seen in the dietary supplement market, produced by such dimetalhydroxy malate-yielding processes as the one described by a 1997
