Keywords： Calcium phosphate ceramics

β-tricalcium phosphate (β-TCP) powder and Na2O-CaO-MgO-P2O5 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.
