球霰石碳酸钙微球的合成及其机理
Synthesis of Vaterite Calcium Carbonate Microspheres and the Crystal Growth Mechanism
摘要
Abstract
High vaterite content of calcium carbonate (CaCO3) microspheres were synthesized by the aqueous solutions of sodium carbonate (Na2CO3) and calcium chloride (CaCl2) in the presence of poly (acrylic acid) (PAA) and sodium dodecyl benzene sulfonate (SDBS) .Morphologies and polymorphs of the precipitated CaCO3were firstly characterized by ordinary technique . Effects of PAA and SDBS concentration on the morphologies and polymorphs of the CaCO3microspheres in the reaction process were investigated ,and the crystal growth mechanism was also discussed .Results show that PAA and SDBS can influence the aggregation behaviors and morphologies of CaCO3in the reaction process ,then a rarely reported crystal growth mechanism of the vaterite CaCO3microspheres is put forward . When the PAA concentration is 1.0g/L and SDBS concentration is 2.5mmol/L ,the high vaterite content of CaCO3microspheres with particle diameters of 5-8μm are obtained .关键词
