Mullite Bricks
Mullite bricks refer to high-alumina refractories with mullite as the main crystalline phase, and the general alumina content is between 65% ~ 75%. It is mainly used for hot blast furnace top, blast furnace body and bottom, glass melting furnace regenerator, ceramic sintering kiln, petroleum cracking system dead angle furnace lining, etc. Mullite bricks have high refractoriness, up to more than 1790 C, and have good thermal shock resistance. There are two types: sintered mullite bricks and fused mullite bricks. The crystallization of fused mullite is larger than that of sintered mullite, and the thermal shock resistance is better than that of sintered products. Aluminum content: 65-90% Standard brick size: 230*115*65mm Compressive strength at room temperature: 100-120MPa Good thermal shock resistance:
