Abstract: A glass ceramic manufactured by sequentially performing the processes of melting and thermal decomposition, water quenching and sintering of a glass composite. The glass ceramic includes 38 wt % to 49 wt % CaO, 41 wt % to 52 wt % SiO2 and 0.1 wt % to 20 wt % P2O5. The glass composite includes a glass component and P2O5, and the glass component includes CaCO3 and SiO2 and does not include an alkali metal oxide. The melting and thermal composition temperature is from 1350° C. to 1650° C. The sintering temperature is from 750° C. to 1050° C. By the combination of CaO, SiO2 and P2O5 and the control of the contents of CaO, SiO2 and P2O5 within the aforementioned ranges, and the glass ceramic contains no alkali metal oxide, the glass ceramic has good mechanical strength and low cytotoxicity.
