1.Made by bauxite clinker and binder through Crushing,Mixing,Shaping,Drying and high temperature Sintering.
2.Al2O3 content is 48%-80%.
3.Main mineral components are corundum and mullite phases.
4.Refractoriness is usually above 1770°C,refractoriness under load is 1420-1550°C.It is a neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion.
5.Working temperature:1350°C -1650°C.
