Lightweight Low Density Mullite Insulating Fire Brick

Mullite brick is a type of refractory brick that is made from the mineral mullite, which is composed of alumina and silica. Mullite brick is known for its high-temperature resistance, strength, and resistance to thermal shock. It is commonly used in high-temperature applications, such as furnaces, kilns, and other industrial processes that require resistance to high heat and thermal cycling.

Mullite brick is made by combining alumina and silica in a specific ratio and firing the mixture at a high temperature. The resulting material has a crystalline structure that is composed of elongated grains of mullite, which gives the brick its unique properties.

Mullite brick is available in different grades, depending on the specific application and requirements. High-quality mullite brick can withstand temperatures of up to 1800°C, making it ideal for use in the most demanding high-temperature applications. It is also resistant to chemical corrosion and erosion, which makes it suitable for use in harsh chemical environments.
