Product Description

Cordierite Corundum Mullite kiln furniture for pusher furnaces and electric furnaces

Corundum mullite kiln furniture (corundum-mullite kiln furniture) refers to a high-alumina refractory product composed of main crystal phases of corundum and mullite. The crystals of corundum are short columnar and barrel-shaped, and they are not interspersed or staggered in the refractory structure. Interlaced columnar crystals of mullite are embedded between the corundum crystals to effectively prevent the slip of the corundum crystals and obtain a stable structure. Because the crystal structure is more stable, it is more conducive to the excellent performance of mullite or mullite and corundum, such as melting point: mullite 1870℃, corundum 2050℃, the eutectic temperature of the two is higher, 1840℃, which is beneficial Improvement and enhancement of high temperature performance of materials.

Corundum mullite kiln furniture

Corundum mullite kiln furniture has uniform thickness, smooth surface, high temperature resistance, thermal shock resistance, high strength, low creep, wide range of operating temperature (1400 ~ 1700℃) and other advantages.Can be processed into various sizes and specifications according to customer requirements, can be used for electronic ceramics, industrial ceramics, high temperature ceramics, magnetic materials and other firing kiln furniture.


The main applications are:
used for electronic ceramics, industrial ceramics, high temperature ceramics, magnetic materials and other firing kiln furniture.

Manufacturing Technique
Corundum Mullite kiln furniture for pusher furnaces and electric furnaces
1.The corundum mullite kiln furniture Production Process
Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment

Synthetic mullite is usually used to make corundum-mullite bricks. Mullite particles can be used as aggregates, α-Al2O3 powder can be used as powder, and fused or sintered corundum particles can also be used as aggregates and synthetic mullite powder. For powder. Aggregate and powder are blended according to a certain ratio and particle size gradation, and sulfite pulp waste liquid is used as a binding agent, and the materials are added in a certain order, fully mixed and uniform, and formed by friction brick press or hydraulic brick press. After the bricks are dried, they are fired at 1650-1750°C.
Some use fused or sintered corundum sand as aggregate, and use bauxite or clay mixed fine powder with high α-Al2O3 composition ratio of mullite or corundum-mullite as powder to make bricks. Products made by this process are slightly less dense, so this process is not widely used.
