以CaHPO4.2H2O和CaCO3为原料,采用固相反应法制备β-磷酸三钙(TCP),并将其掺加到玻璃基生物骨水泥中制成复合骨水泥,浸泡在人体模拟体液(SBF)中,研究其显微结构的变化.结果表明,通过湿式粉碎和固相反应法可以制得晶体发育良好、纯度高的-βTCP粉末;复合骨水泥试样中的-βTCP在SBF溶液的浸泡下会逐步降解,从而制得具有较高孔隙率的骨水泥.
Using CaHPO4.2H2O and CaCO3 as raw materials, β-tricalcium phosphate (TCP) was prepared by solid-phase reaction and incorporated into glass-based bio-cemented bone cement to make composite bone cement soaked in human simulated body fluid (SBF) The results showed that -βTCP powder with good crystal and good crystallinity could be obtained by wet pulverization and solid-phase reaction. The -βTCP in the composite bone cement sample was immersed in SBF solution Will be gradually degraded, resulting in a higher porosity of bone cement.
