Sillimanite brick is a type of refractory brick primarily composed of the mineral sillimanite (Al2SiO5). It is known for its high resistance to thermal shock, high temperature stability, and chemical inertness, making it suitable for use in high-temperature industrial processes. Here are some key characteristics and uses of sillimanite bricks:

Hengli Bubble Alumina Bricks choose high purity bubble alumina as main raw material, high property micro powder as additive, organic material as temporary binder, sintered in high temperature shuttle kiln. The finished products possess large quantity of closed pore, have the characters of light weight & high temperature resistance, low thermal conductivity, high strength, tiny reheating linear change, good thermal shock resistance, good erosion resistance to erosive gas & melting slag.
Bubble Alumina Bricks can greatly improve the furnace heat efficiency, shorten production circle, lighten furnace weight and realize energy saving.

1.High alumina bricks are refractory bricks made primarily from alumina (Al2O3) and other materials, designed for high-temperature applications like furnaces, kilns, and reactors. 
2.Processing: bauxite is used as the main raw material, clinker is sorted by grading and sieved to remove iron, and is prepared by high temperature firing.
3. Manufacturing: Made by mixing raw materials (bauxite or other high-alumina minerals), shaping them into bricks, and firing them at high temperatures. The manufacturing process may include different additives and binders to achieve the desired properties.
4. High alumina bricks are chosen for their durability and efficiency in extreme environments, making them a crucial component in many high-temperature industrial applications.
