Description:High Alumina Lattice Refractory Bricks contain Al2O3 more than 48%, which is made of high grade bauxite through high temperature calcinations. Its refractories is usually above 1770 °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%.
