Highpressure physical properties of magnesium silicate postperovskite 667 (Robie and Edwards 1966). However, a very reasonable alternative is to consider the isotropic approximation.

Because of its high melting point, magnesium oxide finds many uses which apply its refractory properties, so it can be used as a furnace lining and in crucibles. It is also used for fireproofing boarding for panelling walls. Being a metal oxide, magnesium oxide is basic.

Magnesite is a magnesium carbonate mineral with a chemical composition of MgCO3. It is named after the presence of magnesium in its composition. Magnesite usually forms during the alteration of magnesiumrich rocks or carbonate rocks by metamorphism or chemical weathering.

Agriculture. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic lime) is its high solubility, which also allows the option of foliar feeding. Solutions of magnesium sulfate are also nearly neutral, as compared to alkaline salts of magnesium, as .

Magnesium nitride (Mg3N2) has gained extensive attention due to its catalytic and optoelectronic properties. The present investigation was aimed to evaluate the effect of biofield energy treatment on physical and thermal properties of Mg3N2 powder. The Mg3N2 powder was divided into two parts control and treated.
