【摘要】 以分析纯无水硝酸锶和碳酸钠为原料，在旋转填充床中采用液—液相法合成碳酸锶纳米粉体。其条件为：碳酸钠水溶液浓度０．５２５ ｍ ｏｌ／Ｌ，硝酸锶水溶液浓度０．５ ｍ ｏｌ／Ｌ，流量各６０ Ｌ／ｈ，转速０～１ ０００ ｒ／ｍ ｉｎ。得到平均粒径为３０ ｎｍ 的碳酸锶纳米粉体，粒度分布窄。该法过程简单，产率高，易于工业化。更多还原

【Abstract】 Using strontium nitrate(A.R.)and sodium carbonate(A.R.)as raw material,nanometer particles of strontium carbonate were synthesized by mixing the solutions in rotating packed bed.The conditions of the experiment are:the concentration of the solution of sodium carbonate 0.525 mol/L,the concentration of the solution of strontium nitrate 0.5 mol/L,volume of flow 60 L/h respectively,rotating speed 0～1 000 r/min.The average size of the particles is 30～40 nm and the size distribution is very narrow.The process,which has high productivity,is very simple and easy to industrialize.更多还原
