摘要： 对用液相法制备的纳米CaCO3粉末分别用XRD,TEM,IR进行了表征.实验发现,制备的纳米CaCO3呈针状,且分散性较好,为六角晶系的方解石结构.纳米CaCO3粉末的三个IR吸收峰均存在不同程度的蓝移,其中以1 437.3 cm-1处的C-O伸缩振动吸收峰最为明显,达30cm-1.同时,此吸收峰还出现了宽频带强吸收现象.文中对纳米CaCO3粉末红外光谱的变化情况进行了详细的分析讨论.

Abstract: Nanoparticles of calcium carbonate powder prepared by liquid phase process were characterized by XRD, TEM and IR. The results of XRD and TEM showed that the nanoparticles are acicular and highly dispersive and belong to the calcite structure of hexagonal system. The IR spectra revealed that blue shifts are found to different degrees at three absorption peaks among which the C-O peak at 1437.3 cm-1 showing retractable vibration is most obvious, where the blue shift is 30 cm-1 with strong wideband absorption. Discusses in detail the change in infrared spectra of CaCO3 powder.
