Magnesium Oxide

Magnesium Oxide (Magnesia Compound)

Magnesium Oxide (Magnesia Compound) is a white powder material with the formula MgO.

This compound is obtained by heat treatment of either Magnesite (Natural Magnesium Carbonate) or Magnesium Hydroxide. The Magnesium Hydroxide in this case is usually obtained by treating seawater (Magnesium Chloride Solution) with lime. The MgO, obtained through this seawater process, is usually regarded as synthetic and is purer compared to the MgO obtained from Magnesite.

Depending on the degree of the heat treatment, as well as the end-use application, the Magnesium Oxide (Magnesia Compounds) can be reactive and hygroscopic or inert. The calcining temperature of Magnesium Oxide ranges from about 450°C(842℉) up to about 2200°C(4116.44℉).

Reactivity & Classification

Magnesium Oxide, depending on the level of reactivity, has a wide range of applications, from Animal Feed to Refractories. This compound can be classified under the following four broad headings based on reactivity:

Light Burned Magnesia Very Reactive
Calcined Caustic Magnesia Moderately reactive
Hard Burned Magnesia Less reactive
Dead Burned Magnesia Non-reactive or Inert

We offer and deliver Magnesium Oxide of different grades, based on customer’s requirements from 90%up to 99.9% purity.
