The properties of Magnesium Oxide

- Jun 26, 2018 -

Magnesium Oxide is commonly known as magnesia, also known as magnesia, Magnesium Oxide is alkaline oxide, with alkaline oxide generality, belongs to cementitious materials. White powder (light yellow is magnesium nitride), odorless, tasteless, non-toxic, is a typical alkaline earth metal oxide, chemical formula MgO. The white powder has a melting point of 2852 degrees, a boiling point of 3600 degrees, and a relative density of 3.58 (25 degrees Celsius). Soluble in acid and ammonium salt solution, insoluble in alcohol. Solubility in water is 0.00062 g/100 mL (0 C)

0.0086 g/100 mL (30 degree C). Exposed to the air, it is easy to absorb water and carbon dioxide, and gradually become basic magnesium carbonate. Light quality products are faster than heavy quality products. With water, magnesium hydroxide is formed under certain conditions. The pH of saturated aqueous solution is 10.3.
