【摘要】：采用液相沉淀法,以硝酸鉍[Bi(NO_3)_3]為添加劑來調(diào)控碳酸鈣晶體的形狀與大小,制備了海螺狀碳酸鈣粒子.通過掃描電子顯微鏡(SEM)、X射線衍射儀(XRD)、熱重分析儀(TGA)、原子熒光光譜儀(AFS)等對產(chǎn)物的結(jié)構(gòu)和性能進行了表征.結(jié)果表明,在60℃條件下,添加20 mL濃度為2 g/L的Bi(NO_3)_3溶液可得到海螺狀球霰石型碳酸鈣粒子,且其熒光性明顯增強.在碳酸鈣的成核過程中,Bi~(3+)的加入起到了顯著的調(diào)控作用.
[Abstract]:Conch calcium carbonate particles were prepared by liquid-phase precipitation method with bismuth nitrate [Bi(NO_3)_3] as additive to regulate the shape and size of calcium carbonate crystal. The structure and properties of the products were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and atomic fluorescence spectroscopy (AFS). The results show that the conch type calcium carbonate particles can be obtained by adding 20 mL Bi(NO_3)_3 solution at 60 鈩，
