| 摘 要： | 以硝酸铈为氧化剂和抗坏血酸为燃烧剂,采用燃烧法快速合成纳米氧化铈,并用XRD、IR、UV、SEM等技术进行表征.同时进行燃烧剂、煅烧温度、盐助溶剂的考察.得出燃烧法的最佳实验条件为:n(硝酸铈)∶n(抗坏血酸)=1∶2,可以不加助溶剂,不经洗涤、煅烧.在此条件下所制备的氧化铈质量轻,颗粒细.

| Abstract: | With cerium nitrate as the oxidant, ascorbic acid as burners, combustion rapidly synthesized cerium oxides. The sample was characterized by XRD, IR, UV, SEM. The experiment inspected burners dosage,calcined temperature, salt cosoivent impact on samples. The optimum conditions are as follows：molar ratio of cerium nitrate and ascorbic acid is 1 - 2, no adding to cosolvent, neither washing nor calcining. Under this conditions,light weigh and fine grain cerium oxide was obtained. |
