Specification Data of Mullite Brick
Ronghua Refractory offers four grades of mullite insulation bricks, including JM-23 (KR-23), JM-26 (KR-26), JM-28 (KR-28), and JM-30 (KR-30).
Introduction of Mullite Insulation Bricks
Mullite bricks are insulating bricks made primarily from mullite. Mullite is a mineral compound composed mainly of aluminum oxide and silicon dioxide. Small amounts of glass phase, cristobalite, and corundum are also part of its composition. This brick has a unique crystal structure, with aluminum oxide content ranging between 70-78%. It has low impurity content. So, it is a popular choice for raw materials in high-temperature industries.
After firing, the aluminum oxide content in mullite insulation bricks ranges from 42-72%. Its main components include mullite, additives, and others. Mullite insulation bricks exhibit excellent properties such as resistance to acid and alkali erosion, low thermal conductivity, uniform expansion, and so on. Additionally, these insulation bricks have good workability and plasticity. These features enhance convenience in transportation and construction processes.
Delivery of Mullite Insulation Bricks Worldwide
Ronghua mullite insulating bricks are exported to 50+ countries, including South Korea, Ukraine, Singapore, Lebanon, etc.
