摘要：采用一种新工艺———自吸式搅拌反应法制备纳米碳酸钙。通过加入不同的晶形控制剂,合成了立方状、链状、片状、球状、棒状、针状6种不同形状的纳米碳酸钙,并以晶体生长动力学为基础,从添加的种类、用量及添加时间等条件出发,研究了其对CaCO₃产品的粒度和晶形的影响。

Abstract：T he new technology of self-suction stirred reactor to prepare nanometer CaCO₃ is used．T hrough adding different additives nanometer CaCO₃ with six different shapes （including cube chain plate sphere stick and needle） are synthesized． Based on the crystal growing kinetics the influences of additive on CaCO₃ are studied．From the sorts the amount and the adding time the influences of additives on particle size and crystal shape are discussed．
