A new generation of alumina–zirconia nanocomposites (see Figure: brighter phase, ZrO 2 ; darker phase, Al 2 O 3 ) for orthopaedic implants is described. These materials, prepared via a new colloidal synthesis route, are shown to have a high resistance to crack propagation. Thus it may be possible to improve the lifetime and reliability of ceramic joint prostheses.
