摘要
本文分别采用均相沉淀法和共沉淀法合成了碳酸钡粒子。通过添加合适的晶形控制剂,合成了线状、柱状和球状等不同晶形的碳酸钡粉体,利用扫描电子显微镜(SEM)和X射线衍射仪(XRD)进行了表征,并对不同晶形碳酸钡的形成机理进行了初步的探讨。
Barium carbonate was prepared by using homogeneous precipitation method and common precipitation method. Through adding suitable crystal controlling additives, barium carbonates with three different shapes (including fiber, pillar and sphere) were synthesized. The particles were characterized by SEM and XRD, and the synthetic mechanism of barium carbonate with various shapes was discussed.
