The medium-grade magnesia is produced from light burned magnesia with 95% magnesium oxide content by pressing ball, calcining in high temperature shaft kiln and other processes. The product has good sintering degree and is crystallized to dense. It is a high-quality raw material for producing magnesia refractory products.
The refractory temperature of medium-grade magnesia products can reach about 1800-2000 ℃. It is also an alkaline refractory raw material. His products are carefully selected from high-grade and first-grade magnesite ores, which are refined, lightly burned, finely turned, pressed, and fired in a high-temperature shaft kiln. The products can be widely used in magnesia brick and refractory industry
