| Abstract: | The crystalloid growth of precipitated calcium carbonate is inhibited by adding surfactants during the precipitation process. The effects on the average diameter, standard deviation of the precipitated calcium carbonate crystals of the reaction concentration, the types of surhactants and mixing processes of reactants were discussed. The mechanism of inhibitation on the crystalloid growth by adding surfactants was also analysed. |
