Product Description:

75% -80% AL2O3 High Alumina Refractory Brick for Boiler/Klin Lining


Production description 

High alumina refractory brick contain Al2O3 more than 60%, which is made of high grade bauxite through high temperature calcinations. Its refractories is usually above 1750 °C. The main mineral components are corundum and mullite phases. It is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. According to Al2O3 content,it can be divided into three degrees:The Al2O3 content is more than 75%.The Al2O3 content range from 60% to 75%.The Al2O3 content range from 48% to 60%.
