Abstract
For making low density alumina or silica-alumina beads as catalyst support particles for auto-exhaust catalysts, hollow glass spheres of very small diameter are incorporated in the alumina powder mix before it is formed into beads and calcined. The beads may be finished with a surface coat of alumina without the microspheres to improve resistance to abrasion. Preferred beads are made with rehydratable alumina powder.
