Product Description
Fused Bubble Alumina is produced by blowing the melt of high purity Bayer process alumina in a controlled atmosphere to produce hollow spheres. Due to its low density and extremely low thermal conductivity fused alumina bubble is ideal for high alumina based Insulating Bricks and castables.
Its main raw material is high quality alumina powder. After melting
through the electric arc furnace, blowing and then instantaneously
cooling in air, the alumina bubble will have the characteristics of
light weight, closed hole and high temperature resistance. It is
the ideal heat-insulated filler for high temperature furnaces, as
well as the high quality aggregate for high temperature light
refractory castable.
Alumina bubble as the main material can be made into various shapes
of products, with the service temperature 1800 ℃. The finished
products have the high mechanical strength, which is several times
higher than general light products, while its bulk density is the
half of corundum products
