PROPERTIES OF THE COMPOSITE FABRICATED BY THE INTRODUCTION OF SILICONE INTO THE POROUS HYDROXYAPATITE CERAMICS

Abstract

The porous hydroxyapatite (HAp) ceramics were fabricated using the fibrous HAp particles prepared by the homogeneous precipitation method. The silicone was induced into the open pores of porous HAp ceramics by a cold isostatic pressing; then this induced silicone was polymerized by heating at 150°C for 30min. The SEM observation showed that the silicone was present inside the porous HAp ceramics. The resulting HAp-silicone composites were elastically fractured rather than the porous HAp ceramics alone.
