Magnesium sulfate sanderite are rare. Kieserite is a monohydrate and is common among evaporitic deposits. Anhydrous magnesium sulfate was reported from some burning coal dumps. Double salts containing magnesium sulfate exist, for example there are several known sodium magnesium sulfates and potassium magnesium sulfates. An abnormally elevated plasma concentration of magnesium is called hypermagnesemia. Magnesium sulfate Magnesium sulfate is an inorganic salt with the formula MgSO(HO) where 0≤x≤7. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO·7HO), commonly called Epsom salt. The overall global annual usage in the mid-1970s of the monohydrate was 2.3 million tons, of which the majority
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
