High alumina brick
High alumina bricks are produced with selected bauxite chamotte by
advanced process and strict quality control. The main mineral
components are corundum and mullite phases with excellent high
temperature mechanics and chemical corrosion resistance.
Refractoriness under load is normally above ***0~***0°C that is
higher than the fireclay brick and it increases along with the
AL2O3 content. High alumina brick have very good ability of
anti-acidity, anti-metal fluid corrode and anti-oxidation.
High alumina brick are used normally in industry furnaces such as
Blast furnace, hot-blast furnace.
