摘 要：用共沉淀法制备了纳米 ZrO₂ 粉‚采用 Zetaplus 电位 仪分析了4种粉体的表面电性。同时对加入分散剂后的样 品也测试了表面电位‚为粉体的表面改性提供研究基础。 

关键词：纳米 ZrO₂ 粉；表面：Zeta 电位

Abstract：Nano-zirconia powders were prepared by co-precipita tion method‚the surface electricity of four series of samples was atudied by Zetaplus potential instrument．T he surface potential of those samles which had been added dispersant were also de termined．All of these works would provided some valuable data to the research of surface modification．
