在玻璃基水泥中掺加β-磷酸三钙(β-TCP),制成玻璃基复合水泥试样.将该试样放入生理模拟液(SBF)中浸泡一定时间后取出,然后对其微观结构和强度进行了分析研究.结果表明:β-磷酸三钙的加入促进了玻璃基复合水泥中羟基磷灰石(HAP)的生成;随β-磷酸钙掺量的提高,玻璃基复合水泥的显气孔率逐渐增加,而强度则有所下降.
In the glass-based cement mixed with β-tricalcium phosphate (β-TCP), made of glass-based composite cement samples will be placed in the physiological simulated liquid (SBF) soak for a certain period of time removed, and then its microscopic Structure and strength were studied.The results showed that the addition of β-tricalcium phosphate promoted the formation of hydroxyapatite (HAP) in glass-based composite cement. With the increase of β-calcium phosphate content, the glass-based composite cement The apparent porosity increased gradually while the intensity decreased.
