【Abstract】 The spindle shaped calcium carbonate nanoparticles was synthesized in the high gravity reactor. The effects of carbonation parameters on the properties of sedimentation specific volume of the CaCO 3 products were investigated and elucidated by consideration of nucleation and crystal growth kinetics. The key controlling conditions were obtained. The product quality and properties of the CaCO 3 particles synthesized in the high gravity reactor were much better than that of the CaCO 3 particles synthesized in the traditional bubbling stirred tank reactor.更多还原
