英文摘要 | Si-29 and P-31 magic-angle-spinning (MAS) nuclear magnetic resonance (NMR) measurements were employed to investigate crystallization in MgO-CaO-SiO2-P2O5 bioglass-ceramics. The results suggest that wollastonite (beta-CaSiO3) is separated as a new crystalline phase, corresponding to the appearance of a sharp signal in the Si-29 MAS NMR spectra, while oxyapatite (Ca-10(PO4)(6)O) forms in the process of the order of the phosphorus-rich phases increasing as a whole, corresponding to the gradual narrowing of P-31 MAS NMR spectra. ZnO can make the glass stable and difficult to crystallize at a low temperature, while at a high temperature, ZnO can participate in the crystallization of beta-CaSiO3 and promote it.
