Bubble Alumina Description

Bubble Alumina is a high-purity (98.8%) alumina product consisting of hollow spherical particles. Produced by atomizing molten high-purity alumina, the particles form thin-walled, closed-air cells that provide exceptional hot strength and low thermal conductivity, with low bulk density as an inherent advantage. With a maximum service temperature of 1825°C, Bubble Alumina is pre-fired, contains no organics, and exhibits high microwave and RF transparency. Its high alumina content ensures compatibility with aggressive chemical environments, making it an ideal thermal insulator for high-temperature structural applications where insulating performance is critical.
