Sintered Corundum Refractory Brick Description
Sintered Corundum Refractory Brick is a type of high-performance refractory brick made primarily from corundum (Al₂O₃) as the main crystalline phase. Known for its extreme hardness, high melting point, and excellent resistance to wear, corrosion, and high temperatures, this brick is used in highly demanding applications that require durability under harsh conditions. Sintered corundum bricks are produced by sintering high-purity alumina at temperatures typically above 1,700°C to form a dense, stable structure.

Sintered Corundum Refractory Brick Applications
- Steel and Iron Furnaces: Used in areas exposed to high temperatures and corrosive slags, such as ladles, tundishes, and blast furnaces.
- Glass Furnaces: Employed in high-temperature zones due to their heat resistance and minimal interaction with molten glass.
- Cement Kilns: Often used in critical areas of cement kilns where heat and wear resistance are essential.
- Petrochemical Furnaces: Used in linings for high-temperature reactors and furnaces in the petrochemical industry.

FAQs
Q1: What is a Sintered Corundum Refractory Brick?
A Sintered Corundum Refractory Brick is a type of high-temperature-resistant brick primarily composed of silica (SiO₂), with a typical silica content of over 93%. These bricks are known for their excellent thermal stability and resistance to acidic environments, making them ideal for high-temperature industrial applications.
Q2: What are the primary applications of Sintered Corundum Bricks?
These bricks are widely used in steel and iron furnaces, glass furnaces, cement kilns, and petrochemical reactors. They are ideal for areas requiring extreme heat resistance, corrosion resistance, and mechanical durability.
Q3: What makes Sintered Corundum Bricks different from other refractory bricks?
These bricks are made with very high alumina content (often exceeding 90%) and offer superior hardness, low porosity, and excellent resistance to both acidic and basic slags. They are more durable and provide better wear and corrosion resistance compared to standard alumina or silica bricks.
