Controllable preparation of hollow fibrous $$\hbox {SrCO}_{{3}}$$ SrCO 3

A simple and economic $$\hbox {CO}_{{2}}$$ bubbling crystallization reactor for preparation of strontium carbonate $$(\hbox {SrCO}₃)$$ was designed. Through monitoring pH and conductivity, hollow $$\hbox {SrCO}_{{3}}$$ fibres without any morphology control agents were successfully obtained. The effects of temperature and $$\hbox {CO}_{{2}}$$ flow rate on the morphology of $$\hbox {SrCO}_{{3}}$$ were analysed. This study presents a new method for carbonate crystal control and growth.
