| Abstract: | 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. |
