摘　　要：以硝酸锆-尿素为原料,采用溶液燃烧合成(SCS)法制备了超细ZrO2粉末,着重研究了后续煅烧处理对合成的ZrO2粉末结构、尺寸和团聚程度的影响。结果表明,利用SCS法可以合成超细ZrO2粉末,对之进一步进行煅烧处理,可明显降低合成产物中残留有机物的含量,并改善合成粉末的分散性;在700℃煅烧1.0h的条件下,可以获得分散性好,粒径小(<200nm)的ZrO2粉末。Superfine ZrO2 powders were prepared by solution combustion synthesis （SCS） teclanology, taking Zr （NO3）4 and urea as raw materials. The influence of subsequent calcining treatment on the crystal structure, gain size and morphology of the synthesized ZrO2 powders were systemically studied. The results show that superfine ZrO2 powders can be synthesized by SCS technology. Moreover, further calcining treatment of the synthesized ZrO2 powders can obviously decrease the content of residual organism, thereby improve the dispersivity of the powders. After proper calcining treatment （700℃ for 1. 0h）, more dispersive ZrO2 powders with a size of less 200nm have been successfully obtained.
