High Alumina Brick

High refractoriness

High temperature strength

High thermal stability

Neutral refractory

Good resistance to acid and basic slag corrosion

High refractoriness under load

High temperature creep resistance

Low apparent porosity

High alumina brick is a kind of alumina-silicate refractory material with content of alumina oxide more than 48%. It is calcined and formed by the raw material of banxite or the material with high content of AL2O3. High thermal stability, the refractoriness is more than 1770℃.

High alumina brick is mainly used in areas such as kiln linings and walls that require load-bearing and high-temperature resistance, such as in industries such as steel smelting and cement production.
