摘要
The bio-glass in the Na2O-Ca2O-P2O5-SiO2 system involved in tins paper is highly bio-active. The hydrolization of this glass with calcium phosphate and low silica is studied. The structure-composition-property relation of the glass is discussed by means of IR spectrum, DTA and SEM. This study shows that: (a)the structure of the glass is mainly chain-like or layer-like; (b) the glass is separated into a calcium phosphate-rich phase and a silica-rich phase; (c)the chuin- or layer-like structure and the separation hare advantages with hydrolization.
