Once melted, the alumina is atomized with compressed air, which produces hollow spheres. The melting point of Bubble Alumina is approximately 2100ºC. The hollow spheres are chemically inert and have very low bulk density, extremely low thermal conductivity, high hardness, high wear-resistance, and superior insulating properties.

Inhalation exposure to 100 mg/hr aluminium, in the form of powder, or 92 mg Al/ per 2 hr, as a fume, each day for 9-13 months showed a significant retention of aluminium in the lungs of both groups of animals. The aluminium retention in the lungs in rats and hamsters exposed to fume was much greater than when exposed to powder. Following exposure to fresh air, aluminium oxide was cleared
Aluminum Oxide Blast Media | Finishing Systems in York, PA
When used as a blasting media, aluminum oxide is a fused abrasive (brown or white), crushed, screened and sized to meet industry ANSI standards. It is a tough, medium density abrasive known to be cost-effective in blasting processes due to its recyclability, which prevents the need to frequently purchase additional blasting media supplies.
