摘　　要：本文使用氯化钡(BaCl_(2))和碳酸钠(NaCO_(3))为原料,采用植酸作为添加剂制备纳米碳酸钡晶体。通过扫描电子显微镜(SEM)、X射线粉末衍射(XRD)和傅里叶变换红外光谱(FT-IR)等手段对制得的晶体进行了表征。结果表明:植酸能够有效的阻隔碳酸钡晶体的径向生长,形貌由微米级短棒状向鱼卵状碳酸钡聚集体转变,对碳酸钡晶体形貌的合成具有显著的调控作用。该研究为碳酸钡微晶可控合成提供了试验方法,对特殊形貌碳酸钡形貌调控合成具有重要的参考价值。In this study,nano-sized barium carbonate crystals were prepared using barium chloride and sodium carbonate as raw materials with phytic acid as an additive.The crystals were characterized using scanning electron microscopy(SEM),X-ray powder diffraction(XRD),and Fourier-transform infrared spectroscopy(FTIR).The results indicate that phytic acid can effectively inhibit the radial growth of barium carbonate crystals,leading to a morphological transition from micrometer-scale short rods to rosette-like aggregates.It plays a significant regulatory role in the synthesis of barium carbonate crystal morphology.The study provides an experimental method for the controllable synthesis of barium carbonate microcrystals,which holds significant reference value for regulating the morphology of barium carbonate with special shapes during synthesis.
