PROCESS FOR PRODUCTION OF POROUS CERAMIC ARTICLE

摘要

The present invention provides a process for the production of a ceramic shaped implant having a porous layer with interconnected spherical pores on the surface thereof, which process comprises the steps of disposing a porous element having a three dimensionally connected structure made of a heat decomposable material, in which structure, adjacent units share connecting portions and voids, in contact with or adjacent to a ceramic substrate, and filling a space between the ceramic substrate and the porous element and the voids of the porous element with a slurry comprising ceramic powder made from the same material as the ceramic substrate, and then heating to sinter the porous material and the ceramic substrate together.
