摘要
文章描述了立方形纳米碳酸钙制备过程中pH值、电导率的变化情况及碳酸钙的生长过程,并对碳化反应温度、CO2通气量、Ca(OH)2乳液起始浓度、搅拌转速、晶形控制剂种类对CaCO3形貌、粒度、分散性的影响等进行讨论,从而确定了制备立方形纳米碳酸钙的最佳工艺条件。
The variety circumstance of pH and electric conductivity rate and growth process were described during CaCO_3 -preparing.The influence of temperature,discharge of CO_2,thick degree of Ca(OH)_2,the speed of mixing and the kind of additives on facial look,size of particle dispersion of CaCO_3 were discussed.
