Customized Size Alumina Refractory Bricks 65% - 75% Al2o3 CE Approved




Low coefficient of linear expansion

Low thermal conductivity

Strong resistance to the acid slag erosion

Excellent thermal shock resistance

High Refractoriness under load

Low high-temperature creep rate


1. The content of AL2O3 is 65% - 75%.

2. High refractoriness under load. The RUL is higher than fireclay brick as the high content of Al2O3, however, it is lower than silica brick because of mullite crystal does not form reticular tissue.

3. Excellent slag resistance. High alumina brick is a kind of neutral refractory material so it enjoys excellent resistance to acid slag and alkali slag corrosion.

The first-grade high-alumina brick (the aluminum content is not less than 75% refractory brick) is formed by pressing and calcining a high-quality raw material such as high-quality bauxite and alumina. The high-aluminum brick has a refractoriness of over 1790 °C. The load softening temperature is above 1510 °C, the thermal shock stability is good, and the slag resistance is good.
