MID-GRADE MAGNESIA
Mid-grade magnesia is made of super-grade or first-grade magnesite, calcined by light burning, fine grinding, ball pressing, and high-temperature shaft kiln. Its MgO content is greater than 94.5%, with low impurity content and high body density. It is suitable for manufacturing mid-grade magnesia bricks and magnesium indefinite refractory materials.
