| 摘 要： | 以CaCl2和(NH4)2CO3为原料,采用气相扩散法合成碳酸钙晶体。通过添加合适的晶形控制剂,选择适当的用量,合成了花生状碳酸钙晶体。用发射扫描电子显微镜(FESEM)和X射线衍射仪(XRD)进行了表征,结果表明,当控制剂柠檬酸钠用量在10 mmol/L时,生成的花生状碳酸钙粒子粒度分布均匀,在700 nm左右,且粒子分散性良好。并对花生状碳酸钙粒子的形成机理进行了探讨。

| Abstract: | The CaCO3 particles were prepared using calcium chloride and ammonium carbonate by vapor diffusion method. Through adding right crystalline controlling modifiers and selecting right amount,the Ca-CO3 particles with peanut-like were synthesized. The particles were characterized by FESEM and XRD. The results indicated that when the amount of crystalline controlling modifiers（ sodium citrate）was 10 mmol/ L,the calcium carbonate particles with peanut-like which size was uniform and about 700 nm were obtained,the particles decentralize was better. And the synthesis mechanism of CaCO3 particles with peanut-like was discussed. |
