High Alumina Refractory Brick

High alumina refractory brick have 55% ~ 82% alumina content.

The refractoriness under load temperature of high alumina refractory brick is generally  at1420~1550℃, when Al₂O₃ content is added, the refractoriness and refractoriness under load temperature will be improved. High alumina refractory brick have good thermal shock resistance and have good acid and alkali resistance, corrosion resistance and oxidation resistance. They are widely used in various industrial kilns
