What are Corundum Bricks?
Corundum Bricks are a type of refractory brick made from high-quality corundum raw materials. These bricks are specially designed to withstand high temperatures, making them an excellent option for use in areas where other materials may fail. They have excellent thermal shock resistance, making them highly reliable and long-lasting.
The bricks are made of a blend of corundum, mullite, and other ceramic raw materials, which are blended and cut into the desired size and shape. The material is then fired at high temperatures in a kiln to enhance the material's strength and to remove any water or other impurities.
The finished product is highly robust and can withstand temperatures up to 1800 degrees Celsius. The chemical and physical properties of Corundum Bricks make them highly resistant to corrosion, wear, and erosion, making them ideal for use in extreme conditions.
Applications of Corundum Bricks
Corundum Bricks are used in various industries, including steel and iron, petrochemicals, glass, and ceramics processing. They are highly effective in high-temperature environments or places where other building materials cannot withstand the heat.
The primary application of the Corundum Bricks is in the lining of furnaces and kilns. They are known for their ability to withstand a range of temperatures, meaning that they are suitable for use in various furnaces, including blast furnaces, melting furnaces, and rotary kilns.
The bricks also find use in the construction of chimneys and other high-temperature flues. Corundum Bricks are incredibly durable, and their ability to withstand high temperatures makes them an excellent option for building chimneys.
Other applications include the lining of incinerators, boiler systems, and other high-temperature environments where the construction material must be highly resistant to wear and corrosion.
Benefits of Corundum Bricks
Corundum Bricks are the preferred building material in several industries due to their superior properties. Some of the benefits of using these bricks include:
1. High Thermal Shock Resistance- Corundum Bricks can withstand thermal shock, which makes them excellent for use in high-temperature environments where temperature changes can occur rapidly.
2. High Abrasion Resistance - These bricks are highly resistant to wear, making them ideal for use in situations where large amounts of abrasive material are present.
3. Corrosion Resistance- The bricks are incredibly resistant to corrosion due to their chemical composition, making them an excellent option for use in environments where corrosion is a concern.
4. High Refractoriness - The high melting point of Corundum Bricks enables them to remain unaltered in their function even under extreme temperatures reaching 1800°C, making them effective in alleviating stresses in furnaces.
5. Chemical Resistance - Materials used in the manufacturing of Corundum Bricks are chemically inert and do not react with substances used in the chemical industry, therefore it can be used in the refining, synthetic fiber, and other chemical processes.
6. Long-lasting - Corundum bricks are known for their long lifespans, meaning less time is spent on repairs and replacement.
7. Versatile - They can be customized and made into any desired shape to fit specific requirements.
Conclusion
Corundum Bricks are the ultimate solution for high-temperature environments that require a robust, durable, and versatile material. They offer superior protection and durability in furnaces, kilns, and other applications, making them a preferred refractory solution across industries.

Description
Our Corundum Bricks are refractory bricks with high aluminum content made from industrial alumina as the main raw material. They have excellent physical and chemical properties, and have strong resistance to acidic or alkaline slag, metal and glass liquid, so they can also ensure stability when used in various environments. At the same time, they can be divided into sintered corundum bricks and fused corundum bricks according to the basic materials used, which are suitable for different use needs.
Features
In order to better meet the needs of the kiln, we usually add other chemical mineral components in the production process of Corundum Bricks to form composite products, such as zirconium corundum brick, chrome corundum brick, etc. They have good sintering activity, can improve the density and low apparent porosity of the brick, and can ensure a more stable performance in use. In addition, their bending strength is relatively good, and they will not crack or break easily even in a relatively high temperature working environment.
