ABSTRACT:
A sintered material, especially usuable as an abrasive, based on .alpha.-aluminum oxide is produced from Al(OH).sub.3 or aluminum oxide calcined at a lower temperature. Aluminum hydroxide resulting in the Bayer process can be used as the Al(OH).sub.3. The sintered material is distinguished by a crystallite size of standard <0.5 .mu.m, high density and great hardness.
