Magnesium Oxide
Magnesium Oxide, MgO, is a white alkaline earth oxide that can be found as the mineral periclase. It can also be produced via magnesium hydroxide, magnesium carbonate, and magnesium fluoride.
The refractory industry is a major consumer of magnesium oxide, which, when calcined at temperatures between 1500-2000 °C, becomes nonreactive deadburned magnesia, a material that remains stable at very high temperatures.
Other industries in which MgO plays an important role include: agriculture (feed & fertilizer), environmental treatment, and minor medicinal uses.
Agriculture
Magnesium Oxide is largely used as a mineral nutrient for balancing husbandry in animals such as: dairy cattle, poultry, equine, beef cattle, and aquaculture. It is also the most common form of supplemental magnesium used to prevent grass tetany in pastures.
Ceramic, flux:
With a melting point of around 2800 °C (5072 °F), magnesium oxide is one of the highest-temperature melting oxides, but it can be combined with other oxides to achieve lower temperature melts. Characteristics of its final firing results include an opaque matte glaze and pastel colors.
Additional Notes:
* Magnesium hydroxide, Mg(OH)2 thermally decomposes into MgO and water vapor: Mg(OH)2 > MgO + H2O (also see Mg(OH)2)
* Magnesium oxide is also known as magnesia and historically as magnesia alba.
