JM23 insulation bricks

JM23 is a kind of lightweight insulation brick. JM23 mullite bricks have high refractoriness, which can reach over 1790℃. The starting temperature of softening under load is 1600~1700℃. The normal temperature compressive strength is 70~260MPa. Good thermal shock resistance. There are two types of sintered mullite bricks and fused mullite bricks. Sintered mullite bricks are made of high alumina clinker as the main raw material, adding a small amount of clay or raw bauxite as a binding agent, and are shaped and fired. Fused mullite bricks are made of high alumina, industrial alumina, and refractory clay as raw materials, with charcoal or coke fine particles as reducing agents, and are manufactured using the reduction electrofusion method after molding. The crystals of fused mullite are larger than those of sintered mullite, and their thermal shock resistance is better than that of sintered products. Their high-temperature performance mainly depends on the alumina content and the uniformity of the distribution of the mullite phase and the glass.
