Introduction to Alumina Bricks
Alumina bricks are a type of refractory material widely used in various high - temperature industrial applications. They are mainly made from alumina (Al₂O₃), which gives them excellent heat resistance, high mechanical strength, and good chemical stability. These bricks can withstand extremely high temperatures, often up to 1800°C or even higher, depending on the alumina content and manufacturing process.
Alumina bricks are commonly used in industries such as steelmaking, non - ferrous metal smelting, cement production, glass manufacturing, and petrochemical processing. In steelmaking, they line the furnaces, ladles, and tundishes to protect the equipment from the intense heat and chemical corrosion of molten metals. In the cement industry, they are used in rotary kilns to ensure the smooth operation of the high - temperature calcination process.
Now, let's take a look at the 10 leading alumina bricks suppliers in China in 2025.
