Refractory Bricks Manufacturer

Magnesia brick definition. Magnesite brick inquiry is an alkaline refractory material with a magnesium oxide content of more than 85% and periclase as the main crystal phase. Magnesia brick is a refractory brick made of fused magnesia and sintered magnesia at high temperatures.  Manufacture the Refractory Brick MGO QUOTATION. The raw materials for the production of magnesia bricks mainly rely on magnesite. The production process of magnesia brick is to mix dead-burned magnesia with a particle size of less than 5 mm to a fine powder and mix an appropriate amount of sulfite pulp waste liquid or caustic magnesia as a binder. Compression molding under a press. The composition of magnesia brick is metallurgical magnesia, sulfite pulp waste liquid, and caustic magnesia. Metallurgical magnesia is MgO decomposed from magnesite above 1600℃. Its components are, MgO: 92-93.5%, Fe2O3: 1.5-3%, AL2O3: 0.5-3%, CaO: 1-2.5%, SiO2: 2-2.5%.  Manufacture the Refractory Brick MGO Magnesia bricks belong t
