Aluminium oxide hollow ball brick is made of aluminium oxide hollow ball and aluminium oxide powder, by adding compound agglutinant,then formed by vibration and produced by high-temperature sintering.
Features
1.Low volume-weight, high strength, good insulation performance
2.high-temperature resistant, allow direct contact of fire,suitable for various atmosphere
3.high loading softening temperature, low linear change rate after heavy firing
Application:
Lining of high-temperature kilns of industrial ceramics,industrial furnaces under l700℃ of petrochemical, metallurgy and machinery industries.
