ABSTRACT:
Microspheres of activated alumina are thermally and chemically stabilized by soaking the spheres in silicone liquid and decomposing the silicone liquid in an inert atmosphere to leave a silica residue infused in the alumina crystal structure resulting in a silica-alumina phase over the internal and external structure of the alumina. The treated microspheres are then heated in the presence of oxygen to burn off residual carbon resulting from the decomposition of the silicone liquid.
