タイトルまたは説明

Bubble alumina is produced by fusing special high purity alumina.The melt is atomized with compressed air which leads to the hollow spheres.
Bubble alumina is hard but extremely friable with respect to its pressure strength.
The melting point is approximately ***0ºC.Due to its hollow spheres it has a low bulk density and extremely low thermal conductivity.Bubble alumina is chemically inert.
