Synthesis of Amorphous Calcium Phosphate by Sol-gel Method and Examination of its Thermal Behavior

ACP is expected to be useful for a bioceramic in the body because of its high bioactivities. But there is few report about ACP properties. In this study, synthetic method of ACP was investigated in detail. ACP powders were prepared by sol-gel method in N2 atmosphere. ACP powders prepared by sol-gel method were observed its constitutional phase identified by XRD and thermal behavior was examined by TG/DTA. Effect of heat treatment on ACP structure was investigated. Then, specific surface area of synthesized ACP powders was measured by BET method.
