Compared with sintered magnesia, fused magnesia is easier to hydrate.

Sintered magnesia is easily hydrated, and fused magnesia is obtained by melting a special grade A natural magnesite or high-purity light burnt magnesium granule in an electric arc furnace. The product has high purity, large crystal grains, compact structure, strong slag resistance, good thermal shock resistance, and is an excellent high-temperature electrical insulating material. It is also a high-grade magnesia brick, magnesia carbon brick and amorphous refractory material. Important raw materials.

    Fused magnesium is a bending, pressure, high strength, gas hard, gelling material, widely used in defense, pharmaceutical, chemical, paper, shipbuilding and other industries.

    The high-purity magnesia is obtained by purifying and purifying the natural super magnesite ore by light burning, fine grinding, ball pressing and ultra-high temperature oil shaft kiln. It is a high-quality raw material for brick making and indefinite refractory materials. The mid-range magnesia is produced by calcining magnesia with a MgO content of 97% as a raw material, and is subjected to a process such as pressure ball and high temperature shaft kiln calcination. The product has good sintering degree and compact crystal, and is a high-quality raw material for producing medium-grade magnesia refractory products.

    The sintered magnesia is easily hydrated, and the fused magnesia crystals are larger than the crystallization of the sintered magnesia, so the activity is not as high as that of the sintered magnesia.

    Fine powder is equivalent to artificially grinding the grain of the grain. This grain has defects, the activity is larger than the particle, and it is easier to hydrate than the particle.
