摘 要：用共沉淀法制备了两个系列的纳米 ZrO₂ 粉体‚用活 性剂 Duramax ^{T M} D－3021进行了表面处理。采用 SAXS 分 析了样品的晶粒度‚对比分析了样品的红外与拉曼光谱。分 析结果表明‚改性前后纳米 ZrO₂ 粉体的表面特性有很大的 区别。

Abstract：T wo series of nano-ZrO₂ powders were perpared by coprecipitation method‚and activating agent Duramax ^{T M} D － 3021were emplloyed to surface modification．T he grain size was determined by SAXS‚and the samples were also analyzed by in frared and Raman spectrum．All the results indicated that the sr uface performance of nano-ZrO₂powders is notable after samples were employed surface modification．
