Best Answer

Magnesium oxide is used to make linings for some furnaces. It is known as a refractory material - which just means that it is resistant to heat.Magnesium oxide has a high melting point (2852°C) and so resists the high temperatures in a furnace. Its melting point is high because of the strong ionic bonds between the small Mg2+ and O2- ions.

What are the various grades of magnesium oxide?

Magnesium oxide is categorized as a refractory material, which means that it is resistant to decomposition by heat, pressure or chemical attack and retains strength and form at higher temperatures.Rahul Magnesia Pvt. Ltd. is one of the leading manufacturer and supplier of magnesium oxide from India. The company also deals with exports of calcined magnesium oxide, magnesium sulphate, magnesium chloride, magnesium carbonate and light magnesium oxide.Light Burned Magnesium OxideLight burned magnesium oxide is a reactive grade of magnesium oxide that has been calcined at temperatures ranging from 700ºC – 1000ºC. Rahul Mag’s high purity light burned magnesium oxide products have a wide range of reactivity and are used in various applications.Hard burned Magnesium OxideHard burned magnesium oxide is a low reactive grade of magnesium oxide that has been calcined at temperatures ranging from 1000ºC – 1500ºC. Due to its narrow range of reactivity, hard burned magnesium oxide is typically used in applications where slow degradation or chemical reactivity is required.Dead Burned MgODead burned magnesium oxide has been calcined at temperatures ranging from 1500ºC – 2000ºC in a high temperature shaft kiln yielding a material with very little reactivity. Dead Burned Magnesium Oxide products are high purity, dead burned magnesium oxides with high density and low reactivity.Specialty MgOSpecialty magnesium oxides are manufactured to precise specifications in chemistry, size and surface area. Specialty high surface area magnesium oxides are calcined at temperatures below 700°C to produce highly reactive magnesium oxides for use in specialty applications.
