Corundum refractory bricks, also known as corundum fire bricks, are widely used in industries that require high temperature resistance and excellent thermal stability. These bricks are made from high purity corundum, a mineral with a high melting point and exceptional resistance to chemical corrosion.
One of the key advantages of corundum refractory bricks is their ability to withstand extreme temperatures. This makes them ideal for use in furnaces, kilns, and other high-temperature applications. Corundum bricks can withstand temperatures of up to 1800°C, making them one of the most heat-resistant materials available.
Another important property of corundum refractory bricks is their excellent thermal stability. These bricks have a low thermal conductivity, which means they can maintain their strength and shape even in high temperature environments. This makes them highly durable and long-lasting, saving businesses time and money on frequent repairs and replacements.
Corundum refractory bricks are also resistant to chemical corrosion, making them suitable for use in industries that deal with corrosive materials. Their high purity and dense structure help protect against acidic and alkaline substances, ensuring a longer lifespan for equipment and machinery.

Types Of Corundum Brick
Ordinary Corundum Brick
Corundum bricks are refractory products with alumina content greater than 90% and corundum as the main crystal phase. Normal temperature compressive strength (up to 340MPa) is high, load softening start temperature (more than 1700 ℃), good chemical stability, acidic or alkaline slag, metal and glass liquids have strong resistance.
Lightweight Corundum Brick
Lightweight corundum brick is also known as alumina insulation brick, foam corundum brick, or foam alumina brick. It contains more than 90% alumina, mainly composed of corundum lightweight refractory materials. The refractoriness is high, and the volume shrinkage of refiring is small. Compressive strength 4～25MPa, bulk density 0.8～1.35g/cm3. low thermal conductivity. Good thermal shock resistance.
Chrome Corundum Brick
Chrome corundum bricks are corundum refractory products containing Cr2O3. At high temperatures, Cr2O3 and Al2O3 form a continuous solid solution, so the high-temperature performance of chrome corundum products is better than pure corundum products.
Corundum Mullite Bricks
Corundum-mullite bricks are high-alumina refractory products composed of corundum and mullite main crystal phases. The physical and chemical properties of corundum-mullite brick are as follows: Al2O3>85%, Fe2O3 0.45%, apparent porosity 19%, room temperature compressive strength greater than 55MPa loaded softening temperature greater than 1700℃, heating line change (1600℃, 3h)-0.1%, thermal shock resistance (1100℃ water-cooled) greater than 30 times. It has good high-temperature strength, high-temperature creep resistance, thermal shock resistance, and erosion resistance.
Applications Of Corundum Brick
Metallurgy: Sintered Corundum Bricks are used to line furnaces, ladles, and other equipment in the metallurgical industry. They can withstand the high temperatures and harsh conditions encountered in processes like smelting, refining, and alloy production.
Petrochemical: In the petrochemical industry, these bricks are used to line reactors, furnaces, and kilns where various chemical processes take place at elevated temperatures. Their resistance to corrosive gases and liquids makes them suitable for handling aggressive chemical environments.
Cement Industry: Sintered Corundum Bricks are used in cement kilns and other high-temperature equipment in the cement manufacturing process. Their ability to withstand extreme heat and chemical exposure is crucial in maintaining the efficiency of cement production.
Glass Furnace: Glass manufacturing involves high-temperature processes, and these bricks are used to line glass melting furnaces and other equipment. Their ability to resist thermal shock and corrosive molten glass makes them essential for this industry.
Steel Industry: Sintered Corundum Bricks are used in steelmaking processes, particularly in the production of specialty steels. They provide the required refractory lining for equipment like electric arc furnaces, which operate at extremely high temperatures.
Ceramics Industry: In the ceramics industry, these bricks are used to line kilns and other high-temperature equipment for firing ceramics and porcelain. Their stability at high temperatures ensures consistent and controlled firing processes.
Power Generation: Sintered Corundum Bricks can be employed in various components of power generation facilities, such as boiler linings and thermal insulation materials. Their resistance to thermal cycling and high temperatures makes them valuable in this field.
