Alumina Castable

These Castables are kinds of refractory which uses bauxite, andalusite, sillimanite etc. as raw material aggregates and then be mixed proportionately with a binding agent. These castables have extremely high strengths and volume stability at all temperatures. Designed with high proportions of alumina, high-alumina castables contain between 60 to 90 percent alumina. They are much more robust at high temperatures than in basic environments. It can be easily applied in critical area where conventional bricks cannot be laid. It’s mainly used for furnace lining of boiler, blast furnace hot blast stove, heating furnace, ceramic kiln and various industrial furnaces.


  • Good thermal shock resistance
  • High compressive strength
  • Good corrosion resistance
