    Preparation of SnO2 Ultrafine Particles by Spray Pyrolysis Method and Optimization of Technological Parameters

      摘要
    • 摘要: 以SnCl4·5H2O为前驱体,采用喷雾热分解法制备了超细SnO2粉体,研究了反应温度、前驱体溶液浓度和载气流量等工艺参数对粉体粒径和形貌的影响,并对工艺参数进行了优化.结果表明:当反应温度为600 ℃、前驱体溶液浓度为0.6 mol·L-1、载气流量为124 L·h-1时,得到的SnO2粉体平均粒径在1.4 μm左右,粒度分布均匀,结晶度高,球形度好,空心破壳少.

       

      Abstract: With SnCl4·5H2O as precusor,SnO2 ultrafine particles were prepared by spray pyrolysis method. Effects of reaction temperature,precursor solution concentration and gas flow rate on the particle size and morphology of SnO2 particles were investigated. The results show that spherical SnO2 particles with an average size of 1.4 μm,uniform size distribution,good crystallinity and few shells and holes could be obtained under the experimental conditions of reaction temperature of 600 ℃,precursor solution concentration of 0.6 mol·L-1 and carrier gas flow rate of 124 L·h-1.
