【摘要】：采用油水界面法合成纳米β-硅酸钙粉体,研究了钙源、硅源、表面活性剂、回流温度及时间、煅烧温度对合成纳米β-硅酸钙的影响.采用X射线衍射(XRD)和透射电子显微镜(TEM)对所制备粉体的物相、形貌进行表征.试验结果表明,以氯化钙为钙源,硅酸钠为硅源,油酸钠为表面活性剂,75℃下回流2h,800℃下煅烧,获得的纳米β-硅酸钙粉末为空心球结构,该空心球直径为103~338nm,壁厚为9~18nm,且分散性良好.采用油水界面法合成的该空心球结构的纳米β-硅酸钙,有望在生物医用材料领域获得应用.
[Abstract]:Nano-sized 尾 -calcium silicate powders were synthesized by oil-water interface method. The effects of calcium source, silicon source, surfactant, reflux temperature and calcination temperature on the synthesis of nanometer 尾 -calcium silicate were studied.The phase and morphology of the powders were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM).The results show that the nanometer 尾 -calcium silicate powder is hollow sphere structure when calcium chloride is used as calcium source, sodium silicate as silicon source, sodium oleate as surfactant, refluxing at 75 鈩，
