Mullite Brick

Mullite Brick

Mullite Bricks utilize imported plate-like corundum and high-purity fused corundum as their main raw materials. Applying advanced ultra-fine powder addition technology, they undergo processes of blending, drying, and shaping. The bricks are then fired in high-temperature shuttle kilns. Widely applied, Mullite Bricks find usage in equipment such as residue oil gasifiers, second-stage conversion furnaces for synthetic ammonia, carbon black reaction furnaces, and refractory kilns. The product’s dimensional specifications, physicochemical properties, and service life all meet customer requirements.
