Magnesium oxide (MgO) is a widely used compound, primarily derived from magnesite (approximately 93%), with a smaller portion obtained from brine and deep salt deposits (around 7%). The production process typically involves calcination to form periclase, followed by electric arc furnace melting. The resulting material is then selectively crushed and ground to the required particle size, and can be further processed into products of various shapes and pore structures as needed. MgO can be classified into three types based on raw materials and production methods. Among them, FM (fused magnesia) and DBM (dead burned magnesia) are the most commonly used types in the production of high-temperature ceramic components, such as insulation parts, crucibles, and furnace linings. MgO ceramics combine the characteristics of traditional refractory materials with those of advanced ceramics. They offer resistance to alkali metal corrosion and maintain chemical and radiation stability, which makes them suitable for use in nuclear energy and high-temperature processes in metallurgy. The theoretical maximum working temperature is up to 2200\u00b0C, with continuous use in the range of 1600\u20131800\u00b0C. However, MgO ceramics have some limitations, including relatively low thermal shock resistance and high chemical reactivity. They tend to react with oxygen, nitrogen, and water vapor, and their application under vacuum requires strict control of pressure and the selection of inert gases. CONTACAT US Item CCM (Caustic Calcined Magnesia) DBM (Dead Burned Magnesia) FM (Fused Magnesia) Application Industry Magnesium chloride, seawater\u00a0 magnesia Refractory materials industry Refractory materials industry Raw Material Source Magnesium chloride \/seawater magnesia Magnesite High purity (99.83%) dense fine-grained MgO Typical Uses Fertilizers, animal feed, wastewater treatment Shaped\/Unshaped refractories: MgO-C bricks, MgO-Al bricks, gunning mix, taphole clay, etc. High-performance refractories: blast furnace, electric furnace lining, ladle lining,high-temp kilns;Special ceramics,desulfurizer,catalyst carrier Application Scenarios General industrial chemical usage Used as furnace lining in steel,power, glass industries Scenarios requiring higher corrosion resistance and high-temperature strength Example Industries Agriculture, Environmental protection Steel, Power, Glass Aerospace, Energy transition, Infrastructure,\u00a0 Metal refining Features High activity, good reactivity Cost-effective for economic demand scenarios High purity, high density, superior corrosion and high-temperature strength   Ingredient Mixing and Modifications: During preparation, the composition of MgO is carefully adjusted. To improve sintering, slightly increase grain size, and reduce the tendency of hydration, small amounts of additives such as TiO\u2082, Al\u2082O\u2083, or V\u2082O\u2083\u00a0can be added. High-Purity MgO Processing: For applications requiring high-purity MgO ceramics, additives cannot be used. Instead, an activated sintering method\u00a0is applied: Magnesium hydroxide (Mg(OH)\u2082) is calcined at a suitable temperature to create active MgO\u00a0with many lattice defects. This active MgO is then sintered to produce high-performance magnesium oxide ceramics. This method ensures excellent purity and performance, meeting the needs of demanding applications.

To improve sintering, slightly increase grain size, and reduce the tendency of hydration, small amounts of additives such as TiO\u2082, Al\u2082O\u2083, or V\u2082O\u2083\u00a0can be added. High-Purity MgO Processing: For applications requiring high-purity MgO ceramics, additives cannot be used. Instead, an activated sintering method\u00a0is applied: Magnesium hydroxide (Mg(OH)\u2082) is calcined at a suitable temperature to create active MgO\u00a0with many lattice defects. This active MgO is then sintered to produce high-performance magnesium oxide ceramics. This method ensures excellent purity and performance, meeting the needs of demanding applications.
