【 摘 要 】

A simple and economic CO$_2$ bubbling crystallization reactor for preparation of strontium carbonate (SrCO$_3$) was designed. Through monitoring pH and conductivity, hollow SrCO$_3$ fibres without any morphology control agents weresuccessfully obtained. The effects of temperature and CO$_2$ flow rate on the morphology of SrCO$_3$ were analysed. This study presents a new method for carbonate crystal control and growth.
