Magnesium sulfide reacts with oxygen to form the corresponding sulfate, magnesium sulfate. MgS reacts with water to give hydrogen sulfide and magnesium hydroxide. In the BOS steelmaking process, sulfur is the first element to be removed. Sulfur is removed from the impure blast furnace iron by the addition of several hundred kilograms of magnesium powder by a lance. Magnesium sulfide is formed, which then floats on the molten iron and is removed. MgS is a wide band-gap direct semiconductor of interest as a blue-green emitter, a property that has been known since the early 1900s. The wide-band gap property also allows the
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
