High-Aluminum Bricks
Overview of High-Aluminum Bricks 1.High alumina bricks are a type of refractory material widely used in various industrial applications, particularly in the steel, glass, and cement industries. These bricks are made from a mixture of high-quality alumina and other refractory materials, such as clay, silica, and magnesia. The high alumina content in these bricks provides excellent resistance to thermal shock, abrasion, and chemical attack, making them ideal for use in high-temperature environments.Overall, high alumina bricks are a versatile and durable refractory material that offers excellent performance in a wide range of high-temperature applications. Their resistance to thermal shock, abrasion, and chemical attack makes them an ideal choice for industries that require reliable and long-lasting refractory solutions.

High alumina bricks are usually classified into three main grades based on the Al₂O₃ content, which is the primary criterion for judging their performance and applicable scenarios
Grade 1 high alumina bricks with AL2O3 content of ≥75% have the best performance, the highest refractoriness and load-softening temperature, and are suitable for critical parts with ultra-high temperatures
Grade 2 high alumina bricks, with AL2O3 content of 60% to 75%, have a balanced overall performance and high cost performance. They are the most widely used grade in industrial furnaces and kilns
Grade three high alumina bricks, with AL2O3 content 48% to 60% of their performance close to that of clay bricks, have a slightly higher refractoriness and are suitable for medium and high-temperature non-critical areas
