Abstrakt:	The addition of Ca2MgSi2O7 to CaSiO3 bioceramics was investigated in order to modify the dissolution rate of CaSiO3. A series of CaSiO3–xCa2MgSi2O7 composite ceramics with x values of 2, 5, 10, and 20 wt% have been successfully obtained. The effects of Ca2MgSi2O7 addition on CaSiO3–Ca2MgSi2O7 ceramics degradation behavior and apatite formation were comprehensively investigated by means of X-ray diffraction (XRD), scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM/EDS), Fourier transform infrared spectroscopy (FTIR), and inductively coupled plasma optical emission spectrometry (ICP-OES). The results showed that the dissolution rate of the achieve system ceramics gradually decreased in succession, and the apatite-forming was delayed by the addition of Ca2MgSi2O7. The suitable dissolution rate and apatite-forming ability of CaSiO3–Ca2MgSi2O7 bioceramics can be expected, indicating that the addition of Ca2MgSi2O7 to CaSiO3 bioceramics may be a promising route for modifying the dissolution behavior and apatite-forming ability of CaSiO3 bioceramics.
