Abstract : The patent application discloses a technique for producing a ceramic bone implant of high aluminum oxide material having a high degree of controlled pore structure suitable for accepting bone tissue ingrowth. A high porosity, fully reticulated polymeric sponge is infiltrated by a viscous slip of high aluminum oxide ceramic material having a foaming agent and catalyst therein; the slip is then foamed by controlled decomposition of the foaming agent. The material is dried slowly to prevent skrinkage cracks and is then sintered.
