High purity light burned magnesium powder

Medium grade magnesia is made from light burned magnesia with 95% MgO as raw material by pressing ball and calcining in high temperature shaft kiln. Light burned magnesia powder has good sintering degree and dense crystal, which is a high-quality raw material for producing medium grade magnesia refractory products. The fire resistance temperature of medium grade magnesia products can reach about 1800-2000 ℃. It is an alkaline refractory raw material. Its products are carefully selected from super grade and first grade magnesite ores, which are purified, lightly burned, finely ground, pressed with balls, and secondary sintered in a high-temperature shaft kiln. The products can be widely used in the magnesium brick and refractory industry.
