Abstract
In the previous study, we reported the result to prepare lithium carbonate powder from various lithium-contained solution. Therefore, using the lithium hydroxide solution, it is conformed that the reaction could occur thermodynamically, and the recovery rate of lithium was 89.4 %. In this study, we carried out the experiment to prepare lithium carbonate powder through gas-liquid reactions with lithium hydroxide solution and CO2 gas using ultrasound energy. In case ultrasonic energy is applied to the reaction of lithium carbonate, the recovery rate of lithium at room temperature was approximately 83.8 %, and the recovery rate of lithium was greatly increased to approximately 99.9 % at 60℃ reaction temperature. And when ultrasonic energy is not applied, the particle size of lithium carbonate powder was 7.7 ㎛ in D50. But the particle size of lithium carbonate powder was significantly reduced to 8.4 ㎛ in D50 under the influence of ultrasonic.
