ABSTRACT:
By adding very-finely-divided or highly-dispersed titanium dioxide or aluminum titanate, optionally in a mixture with aluminum oxide, sintered products of great hardness, whose fracture toughness can be adjusted over a wide range, are obtained from aluminum hydroxide according to a sol-gel process depending on the selection of the sintering conditions. The materials are especially suitable as abrasives or for the production of ceramic powder or components.
