PURPOSE:To easily obtain bioceramics having a low Young's modulus and hardly causing cracking when embedded in a bone in a living body by adding a specified amt. of Ti to tricalcium phosphate and carrying out granulation, molding and sintering at a prescribed temp. CONSTITUTION:Ti is added to tricalcium phosphate in 0.01-0.2 atomic ratio of Ti to Ti+Ca. The resulting powder is granulated, molded and sintered at 900-1,300 deg.C to obtain bioceramics. Since Ti is incorporated into a tricalcium phosphate sintered body having a high Young's modulus, a Ti-contg. tricalcium phosphate sintered body having a low Young's modulus can be produced. When the bioceramics is embedded in a bone in a living body, cracking due to the difference in Young's modulus between them can be inhibited over a long period of time. |
