Anti-spalling high alumina brick

Introduction
Anti-spalling high alumina brick uses special grade high-alumina bauxite with certain synthetic compost material containing ZrO2 as its raw material and after adding certain ration of these raw material to mould, then high pressure forming, finally be burned under high temp.

Characteristic
1.Strong anti-spalling resistance
2.Excellent corrosion resistance from Na, kalium, alkali salt, etc
3.Good thermal shock resistance
4.Low thermal conductivity
