1,Description of Mullite-SiC Brick:
The product using fused SiC,Sintered mullite sand,corundum sand and calcined bauxite as raw materials. by high pressure shaping and high temperature firing. Product has good thermal shock resistance, high thermal conductivity, good corrosion resistance and high chemical stability etc trait. It is widely used in heat treatment furnace, glass annealing furnace, enamel sintering furnace and other industrial furnace.
2,Index of Mullite-SiC Brick
| Item | Mullite-SiC brick | Corundum-SiC brick | High Alumina-SiC brick |
SiC% | ≥20 | ≥20 | ≥20 |
Al2O3% | ≥65 | ≥70 | ≥55 |
Fe2O3% | ≤1.0 | ≤1.0 | ≤1.5 |
Bulk Density g/cm³ | ≥2.3 | ≥2.6 | ≥2.5 |
Apparent Porosity% | ≤20 | ≤22 | ≤20 |
Cold Crushing Strength MPa | ≥80 | ≥100 | ≥80 |

3,Product knowledge:
According to the different content of alumina and production process, products are divided into high-purity mullite silicon carbide brick, corundum silicon carbide brick, high-alumina silicon carbide brick.The main raw materials of high purity mullite silicon carbide bricks are fused mullite sand, andalusite sand and high purity silicon carbide sand,adding metal silicon and ultrafine powder, the product matrix is strengthened and the microstructure of the product is improved.Corundum silicon carbide brick is made of fused white corundum sand and high purity silicon carbide sand as the main raw materials,which improves the content of alumina, strength and wear resistance of the product.The performance of high alumina SiC brick is slightly worse than that of mullite SiC brick and corundum SiC brick.
4,Main features of the product:
1),The apparent porosity plate is low.≤20%
2),High density, density≥2.5g/cm3
3),High wear resistance
4),High temperature performance,refractoriness under load≥1600℃
5),Thermal shock resistance is very good.
5,Main uses of products:
Dry quenching coke oven,electrolytic aluminium cell, garbage incinerator, annealing furnace, etc.
6.Good feedback of product use effect,the products have been exported to Russia, Australia, Oman
