Bubble Alumina Tube Description

Bubble Alumina Tube 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 which combine to give it exceptional hot strength and 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.

Properties:

-High Hardness

-Abrasion / Wear-Resistance

-Chemical Inertness

-Superior Insulating Properties

-Resistance to Thermal Shock
