High-purity magnesia

High-purity magnesia is produced by selecting premium-grade magnesite, which undergoes light calcination, fine grinding, dry pelletizing, and sintering in a super-high-temperature vertical kiln. With MgO content exceeding 97%, it features directly bonded periclase crystals and a dense structure, making it an ideal material for manufacturing high-grade alkaline bricks and unshaped refractories.
