What Are the Refractory Products with Mullite as the Main Crystal Phase?

Mullite is an important refractory material that is widely used in the preparation of refractory products due to its excellent high-temperature stability and fire resistance. The following are some common refractory products with mullite as the main crystal phase:

Mullite bricks: This is one of the common refractory products with mullite as the main crystal phase. Mullite bricks have good high-temperature stability and corrosion resistance and are widely used in the lining of various high-temperature industrial furnaces, glass kilns, and other equipment.

Mullite castable: Mullite castable is a castable refractory material whose main components are mullite particles and refractory binders. It has good fluidity and is suitable for lining equipment with complex shapes, such as curved parts of kilns.

Mullite ceramic products: Mullite ceramic products are often used in some high-temperature sintering or heat treatment processes, such as the lining of sintering kilns and ceramic kilns. They generally have higher fire temperature resistance and stability.

Mullite fiber products: Mullite fiber is a high-temperature fiber commonly used in insulation and fire-resistant applications. They can be formed into felts, blankets, boards, etc. and are used to provide insulation and thermal insulation properties.

Mullite ceramic filter plate: Mullite ceramic filter plate is often used in the metal melting and casting process to filter and purify molten metal.

The refractory products listed above all have mullite as the main crystal phase. They perform well in high-temperature environments and have good corrosion resistance, so they have been widely used in various industrial fields.
