The stick-like nano-CaCQ3 was prepared by carbonization, with A1Cl3 and EDTA as crystal control and dispering agent Effect of AlCl3 s content on product s apperance and performance such as DOP absorption, activation and sedimentation volume was studied. The results show that, when the amount of AlCl3 is 1. 5%, the DOP absorption comes to its lowest, it is 72mL/100gf when the amount of AlCl3 is 2. 0% and the amount of EDTA is 1%, the sedimentation volume comes to its highest, it is 4. 04mL/g; when the amount of AlCl3 is less than 1. 5%, the activation changes little with the increasing of AlCl3, when the amount of AlCl3 is more than 1. 5%, the activation rudu-ces obviously with the increasing of AlCl3. SEM and XRD show that the product is stick-like nano-CaCQ3.
