AC3490 Bubble Alumina

Bubble Alumina Description

Bubble Alumina is produced by atomizing melted high-purity alumina. The atomized particles form hollow spheres. Bubble Alumina, by nature of its structure, has very low thermal conductivity and low bulk density. While Bubble Alumina exhibits a bulk density twice that of a premium-grade alumina fiber insulator. Bubble Alumina’s structure consists primarily of closed air-filled thin-walled cells that combine to give it exceptional hot strength low thermal conductivity. This makes Bubble Alumina an effective high-temperature thermal insulator in structural applications where insulating capabilities cannot be sacrificed and appropriate for use at temperatures as high as 1825°C. It is pre-fired, contains no organics, and exhibits high microwave and RF transparency. Its high alumina content makes it compatible with many extreme chemical environments.
