Abstract
Hollow aluminum bubbles (closed spherical shells) with diameters up to several micrometers and wall thicknesses of about 15–30 nm have been obtained. The bubbles are formed on the surface of aluminum particles covered with a layer of aluminum hydroxide upon heating to ~750°C in an oxygen-containing atmosphere.
