摘要
在分析纳米CeO2各种性质的基础上，研究了不同分散剂对纳米CeO2的表面电性及平均粒度的影响，并对分散机理进行了分析。结果表明：添加无机电解质及组合使用离子型表面活性剂和非离子型表面活性剂可以使纳米CeO2在弱碱性水介质中保持良好的分散性。
It is investigated that the surface potential measurement and mean size of ceria nanopowder were affected by different dispersant on base of analying various property of ceria nanopowder. The dispersion mechanism is also analysed, As a result, When different inorganic electrolyte and combined use of ionic and nonionic surfactants are applied, excellent dispersion system of alkalescent aqueous medium can be obtained.
