模拟生物矿化制备球形碳酸钙粒子及表征

Biomimetic preparation and characterization of spherical CaCO_3 particles

模拟生物矿化原理,以磷酸酯(DDP)作为有机质,采用碳化法制备了具有球形CaCO3粒子。通过场发射扫描电子显微镜(FESEM)、X射线衍射仪(XRD)、傅立叶红外光谱仪(FT-IR)、热重(TGA)及活化指数等检测手段对所得CaCO3粒子的形貌、晶型及性能进行了表征。

In the work, the dendrite-shaped aragonite CaCO3 particles have been prepared biomimetically via the carbonation route in the presence of DDP. The as-prepared products were characterized with FESEM, XRD, FT-IR, TGA and the active index. The possible growth mechanism of the dendrite-shaped aragonite particles was discussed.
