Introduction of products
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 with the following specifications:
