The effects of various pH values of sodium phosphate buffer solution (PBS), 4.0, 6.0, 8.0, and 9.0 on calcium phosphate cement (CPC) prepared by mixing monocalcium phosphate monohydrate (MCPM), calcium carbonate, and PBS were studied. The phase evolution takes place in three steps: Firstly, the MCPM and calcium carbonate crystals dissolve in the PBS and precipitate in the form of DCPD crystals. Then, after 12 h, DCPD begins to convert to amorphous calcium phosphate (ACP). Finally, the metastable ACP phase converts into stable CDHA. With an increase in the pH of the PBS, the CDHA content in the CPC increased.
