What's the refractory brick

Refractory brick refers to high alumina brick containing Al2O3 more than 48%, which is made of high grade bauxite through high temperature calcination. Refractory brick is a kind of neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion. It has characteristic of high refractory under load, It make it an ideal material for various kinds of industrial furnace.
