A study on improvement of bioactivity of CaO–Na2O–SiO2–P2O5 glasses for applications for bone substitute |
초록 |
The compositional dependences of bioactivity, thermal properties, atomic structure, and surface morphology have been investigated in the CaO–Na2O–SiO2–P2O5 system; this system is known as a bioglass. 45S5 Bioglass® is known to be a general and highly bioactive material. However, the bioactivity of this glassy material is expected to be improved by modifying the alkali-metal composition. Thermal properties, density, and molar volume were measured to investigate the structural packing. FT-IR spectra and X-ray diffraction were used to confirm the structures of these glasses. The morphology was examined using scanning electron microscopy, and the formation of a Ca–P layer was studied using an energy-dispersive system. This study shows that the tendency to form a calcium phosphate layer is increased with the substitution of Na2O for K2O. |
