Series of Spalling Resistant High Alumina Brick

June 11, 2018
Spalling resistant high alumina brick uses superior bauxite clinker and ZrO2 containing synthetic material as raw material, which is under high press molded according to a certain ratio.
Spalling resistant high alumina brick is with strong spalling resistant and anti- K, Na, S, Cl, and alkaline salt erosion, low thermal conductivity and other properties. It's the ideal material for cement kiln transition zone and decomposition zone, it can be also used in cement kiln door cover and cooler parts.
Jundao (Henan) New Materials Co.,Ltd manufacture and supply quality high alumina bricks with features of good spalling resistance, good chemical & erosion resistance, low creep, good thermal shock resistance etc. We've exported to all over the world.
