摘要
β-tricalcium phosphate （β-TCP） powder and Na20-CaO-MgO-P205 glass binder were synthesized and mixed, and then the biodegradable porous calcium phosphate ceramics were successfully prepared by foaming and sintering at 850℃. The as-prepared ceramics possess a high porosity with partial three-dimension interconnected macro- and micro-pores. As in vitro experiment testified, the calcium phosphate ceramics （CPCs） has good degradability.
