Refractory materials generally refer to inorganic non-metallic materials with a fire resistance of over 1580 ℃, capable of withstanding various physical and chemical changes and mechanical effects.

Why use Magnesium Oxide for refractory materials

Magnesium Oxide is a white lightweight powder, odorless, and easily absorbs water and carbon dioxide when exposed to air. It is soluble in acids and ammonium salts, insoluble in water and ethanol, with a melting point of 2800 and a boiling point of 3600. Magnesium oxide has high fire resistance and insulation properties, a high melting point, and extremely high stability, resistance to oxidation, reduction, and thermal decomposition. It can be said that it is non fuel. Meanwhile, due to its stability, non reactivity with water, and low cost, magnesium oxide is widely used as a refractory material.
