OS0605 Fabrication and Evaluation of Artificial Bone Composite of Calcium Phosphate and Reef Building Coral
Details
Artificial bone is used in the treatment of bone fractures and bone tumors. Hydroxyapatite is widely in the artificial bone. The apatite, has the ability to bind to the bone. Dense body is used to the area in need of strength. On the other hand, the porous material is used for the site reactions with body fluids such is required. However, both of the high reactivity and high strength is difficult. In this study, Fabrication of artificial bone composite of coral and HAp is the objective. The addition amount of coral is 10%. Composite artificial bone was sintered at 1300℃ 5 hours. It was possible to produce composite artificial bone. However, the sintered body was collapsed in about ten days. The reason for this is that it is fired at a high temperature. In other words, carbon dioxide elimination of coral is the cause. Furthermore, it is to the adsorbed moisture in the air. Crystal structure is changed to calcium oxide. As a structure, I expand. This is related to the collapse.
