Andalusite is a kind of alumina silicate mineral. lt's one of the Kyanite series mineral (include andalusite, silimanite, kyanite), main contents are Al2O3 and SiO2.
Andalusite has great thermal shock resistance, stable volume, high strength, great erosion and corrosion resistance, great slag resistance and high refractoriness under load.
It's widely used as raw materials for monolithic refractories, high alumina refractory bricks for hot blast furnace, copper smelting furnace etc.
