Main Compositions of mullite refractory bricks are 60%-75% Al2O3 and 24%-35% SiO2. Al2O3 has high melting point and brings higher heat resistance for mullite brick. SiO2 is a kind of acid material, which enhances corrosion resistance of mullite brick. Mullite refractory brick is a kind of high-grade refractory material. The refractoriness is as high as 1790℃ (3254℉).
Another important function of SiO2 is to combine Al2O3 and form mullite phase. Kerui firebrick supply controls compositions of mullite brick accurately. As a result, Kerui can supply fire bricks that have high properties.
Kerui provides different kinds of mullite refractory bricks for sale. With annual output of 150,000 tons, Kerui has the ability to large-scale production of mullite bricks.

Sintered mullite refractory brick refers to putting molded mullite brick into tunnel kilns for drying and sintering. Kerui intelligent PLC system controls the temperature and position of bricks in tunnel kilns. The structure of sintered mullite refractory brick is denser.
For fused mullite refractory brick, original mullite will be melted in electric furnace and then poured into molds. After fusing, the purity of mullite brick is higher. Fused mullite brick is suitable for customers who have higher requirements.
Kerui corundum mullite brick is a special material mixed with corundum and mullite minerals. Corundum is a very hard mineral and this brick has high compressive and flexural strength.
Kerui mullite refractory bricks can withstand high temperatures of at least 1790℃ (3254℉). It means Kerui mullite refractory brick have high refractoriness and high resistance to thermal shock.
The chemical composition of mullite is dense and hard, which forms good creep resistance. This means it maintains its shape and dimensional stability even when subjected to long-term thermal loads. This property is crucial for applications where the refractory material is subjected to constant stress and high temperatures over extended periods.
One of the remarkable mullite bricks properties is its resistance to chemical corrosion. It exhibits excellent stability when exposed to acidic or alkaline environments, making it suitable for applications where corrosive gases, liquids, or solids are present. The brick’s chemical resistance helps maintain its structural integrity and performance over extended periods, reducing maintenance needs and enhancing operational efficiency.
It has good electrical resistivity. Therefore, it’s an ideal choice for applications that require electrical insulation. This high temp fire brick effectively prevents the flow of electric current and the conduction of charges, contributing to enhanced electrical safety and performance. This characteristic is particularly valuable in electric furnaces, resistance heating systems and other electrical equipment operating in high-temperature environments.
In the steel and iron industry, Kerui mullite bricks properties are able to bear intense heat generated during the steel and iron making process and ensure structural integrity. When used in steel and iron industry, this brick is suitable for blast furnaces, hot blast stoves, steel ladles and so on.
Actually, the mullite brick is significant in glass industry. Because this brick has excellent resistance to chemical corrosion. In glass manufacturing, these bricks are used in the refractory linings, construction of furnaces, tank regenerators, checkers and many other parts of glass making furnaces.
The cement manufacturing process has high requirements on the hardness of brick. Because it will cause strong shock and abrasion. The mullite refractory bricks from fire bricks manufacturing contribute to the overall efficiency and durability of the cement manufacturing process.
To withstand the intense heat and corrosive conditions in power industry, customers had better choose mullite brick for the high temperature kiln. This brick can also help maximize energy efficiency and reduce heat loss in power plants.
The non-ferrous industry requires mullite bricks with high melting points and resistance to chemical corrosion. Therefore, Kerui mullite refractory bricks atre extensively employed in the construction of smelting furnaces, converters, refining vessels and other positions.
Due to thermal shock and erosion by acidic gases caused in environmental equipment, Kerui mullite bricks play a significant role. When customers use this brick in waste incineration and hazardous waste treatment facilities, it can realize safe and effective production.
No, Kerui mullite refractory brick is NOT expensive! It’s well-known that Kerui provides affordable mullite refractory brick in this industry.
