Abstract
A new generation of alumina-zirconia nanocomposites (see Figure: brighter p hase, ZrO2; darker phase, Al2O3) for orthopaedic implants is described. The se materials, prepared via a new colloidal synthesis route, are shown to ha ve a high resistance to crack propagation. Thus it may be possible to impro ve the lifetime and reliability of ceramic joint prostheses.
