MAGNESIUM OXIDE

Magnesium oxide (MgO) is also called as magnesite. Its information is as follows: density 3.58g/cm3, white powder, melting point 2852℃, boiling point 3600℃, soluble in acid and ammonium salt, insoluble in water and ethanol, and easy deliquescence in air. Its specific surface area is 180cm2/g at the calcining temperature of 400℃as well as only 3cm2/g at 1300℃. It is an air hardening cementing material.
Application
