High alumina brick refractoriness under load is normally around 1420~1550°C which is higher than fireclay brick and it increases along with the AL2O3 content increase.

High alumina brick have very good ability of anti-acidity, anti-metal fluid corrode and anti-oxidation.
High alumina brick is mainly used in industry furnaces such as Blast furnace, hot-blast furnace and EAF etc.
