Study on the Synthesis of High Quality Nanometer Calcium Carbonate Using Ultrasonic Technology

摘要

The synthesis of nanometer calcium carbonate was strengthened using ultrasonic technology. In the presence of ultrasonic, the effects of initial reaction temperature, density of Ca(OH){sub}2 and flow rate of CO{sub}2 on nanometer calcium carbonate particles' size were investigated in this paper. The homogeneous dispersion nanometer calcium carbonate particles which size were 20～30nm were synthesized using ultrasonic reactor.
