摘要
本文研究了Mg~(2+)对气-液法制备的碳酸钙晶型和形貌的影响,使用SEM、XRD和FT-IR分析表征了碳酸钙样品。结果表明,Mg~(2+)可有效地提高霰石的产量,促进球霰石的产生,形成粒度均匀并分散的颗粒。
This paper studied the influence of Mg~(2+) on the crystal and morphology of calcium carbonate prepared by gas-liquid method. The samples were characterized by SEM, XRD and FT-IR.The results show that Mg~(2+) can effectively increase the production of aragonite, promote the production of spherical aragonite, and form particles with uniform and dispersed granularity.
