High-purity magnesia is made of special grade magnesite, which is sintered by light burning, fine grinding, dry ball pressing and ultra-high temperature oil shaft kiln. The MgO content is greater than 97%, the impurity content is low, the periclase crystals are directly combined, and the structure is dense. The main function of high-purity magnesia is to produce high-grade alkaline bricks and ideal raw materials for unshaped refractories. Magnesia carbon brick price
Fused magnesia is made by selecting special grade magnesite or special grade light burnt magnesia powder as raw materials and melting it at high temperature in an electric arc furnace. The periclase is well-developed, large crystals, high direct bonding rate, compact structure, strong slag resistance, and excellent high-temperature volume stability. The main function of fused magnesia is to produce excellent raw materials for magnesia carbon bricks, advanced alkaline bricks and unshaped refractory materials. It is graded according to the MgO content of 96-98%.
