Fused Alumina Bubble

1.Description：

Fused alumina bubble 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.

2.Characteristics：

Fused Alumina Bubble is characterized by low density, extremely low thermal conductivity.

3.Application：

Fused Alumina Bubble is ideal raw material for high alumina based insulating bricks and castables.
