High aluminum fire brick

If Al2O3 content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries set the lower limit of Al2O3 content for high-alumina refractories at 42%. In China, according to the content of Al2O3 in high alumina bricks, it is usually divided into three grades: Grade I -Al2O3 content>75%; Grade II-Al2O3 content is 60~75%; Grade III-Al2O3 content is 48-60%.

The characteristics of high alumina bricks

a. RefractorinessThe refractoriness of high alumina bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750~1790℃, which belongs to advanced refractory materials.

b. Load softening temperatureBecause high-alumina products have high Al2O3, less impurities, and less fusible glass bodies, the load softening temperature is higher than that of clay bricks. However, because mullite crystals do not form a network structure, the load softening temperature is still not as high as that of silica bricks. 

c. Slag resistanceHigh alumina bricks contain more Al2O3, which is close to neutral refractory materials, and can resist the erosion of acidic slag and alkaline slag. Because of the inclusion of SiO2, the ability to resist alkaline slag is weaker than that of acidic slag
