Properties of Magnesium Oxide

Properties of Magnesium oxide: Magnesium oxide is commonly known as bitter soil, also known as Magnesium Oxygen. Magnesium oxide is an alkaline oxide, which has the general properties of alkaline oxide and belongs to cementitious materials. White powder (light yellow magnesium nitride), odorless, odorless, non-toxic, is a typical alkaline earth metal oxide, chemical formula MgO. The white powder has a melting point of 2852 C, a boiling point of 3600 C and a relative density of 3.58 (25 C). Soluble in acid and ammonium salt solution, insoluble in alcohol. The solubility in water is 0.00062 g/100 mL (0 degree C)

0.0086 g/100 mL (30 degree C). When exposed to air, it is easy to absorb water and carbon dioxide and gradually become basic magnesium carbonate. Light products are faster than heavy products. Magnesium hydroxide is formed when combined with water under certain conditions, showing a slightly alkaline reaction. The pH of saturated water solution is 10.3. Soluble in acid and ammonium salt, insoluble in water, its solution is alkaline. It is insoluble in ethanol. It has strong refractivity in the visible and near-ultraviolet light range. Magnesite (MgCO3), dolomite (MgCO3. CaCO3) and seawater are the main raw materials for the production of magnesium oxide. Magnesium oxide is obtained by thermal decomposition of magnesite or dolomite. Magnesium hydroxide is precipitated from seawater treated with lime, and magnesium hydroxide is obtained by burning magnesium hydroxide. Magnesium hydroxide or basic magnesium carbonate can also be precipitated from magnesium chloride brine or brominated brine obtained from comprehensive utilization of seawater by adding sodium hydroxide or sodium carbonate, and then calcined to obtain magnesium oxide. China mainly uses magnesite, dolomite, brine or brine as raw materials.

Magnesium oxide has high refractory and insulating properties. It can be transformed into crystals by high temperature burning above 1000 C [1]. When it rises to 1500 - 2000 C [1], it will become dead burnt magnesia (that is, magnesia) or sintered magnesia.
