摘要:

以羧甲基纤维素钠(CMC)为晶型控制剂合成微米级球形碳酸钙, 并考察不同因素对产物形貌和粒径的影响, 得到了合成球形碳酸钙的最佳条件. 采用X射线衍射、 红外光谱和扫描电子显微镜等方法对样品进行表征.  结果表明: 合成的碳酸钙晶型主要为方解石, 并有少量球霰石; 产物的球形度较好且粒径均一, 粒径为1~3 μm.

关键词: 晶型控制剂, 羧甲基纤维素钠, 微米级球形碳酸钙, 最佳条件

Abstract:

Spherical calcium carbonate particles were prepared with sodium carboxymethyl cellulose (CMC) as crystalline control agent. Effects of different factors on the morphology and particle size were studied and  optimal synthesis conditions of spherical CaCO3 were obtained. XRD, FTIR, SEM were used to characterize the product. The results indicate that the spherical particles  mainly consisted  of calcite mixed with a small part of vaterite, and the product has good sphericity and uniform particle size in a  range of about 1—3 μm.

Key words: crystalline control agent, sodium carboxymethyl cellulose (CMC), micron spherical particle CaCO3, optimal condition
