The introduction of silver into calcium phosphate bone cement (CPC) increases the strength and antimicrobial activity of the material. In this study, we synthesized silver-containing CPC by introducing silver phosphate salt Ag3PO4 in the cement powder with an Ag/Ca atomic ratio equal to 0.05. α-Tricalcium calcium phosphate (α-TCP, Ca3(PO4)2) and Hydroxyapatite (HA) were mixed with dicalcium phosphate dihydrate (DCPD, CaHPO4.2H2O) to form the cement powder. Deionized water (DI) solution was used as the cement fluid. CPC based on silver containing apatite phase was obtained. The phase composition and setting time of the cement was determined. The formation of apatite was verified by XRD and FTIR analysis, the initial and final setting times of the cement are 11 and 35 min.
