本文利用有机高分子作为模板，硝酸铈和碳酸氢铵为原料，控制合成超细氧化铈。通过对PSS浓度、加料方式、陈化时间等的研究寻找最好的制备条件。采用扫描电镜、粒度仪、比表面积仪等手段进行了表征。结果表明，利用有机物PSS为模板剂合成的超细氧化铈的条件为：正加，搅拌速度为300r/min，陈化时间为3h。 采用本方法制备出的氧化铈为薄片状颗粒，当PSS浓度为0.5mol/L是效果最好，但由于时间有限，不能考虑其他制备条件，所制颗粒形状不规则，有待进一步研究。 [ Last edited by srdong1233 on 2010-6-16 at 16:47 ] |

翻译如下： This text take organic polymer as a template ，cerous nitrate and ammonium bicarbonate as raw materials，controlling synthetize superfine cerium oxide . we try to determine the best Preparation Conditions by conducting research to find the optimal consistency of PSS , charging style and value of aging time .Characterised by scanning electron microscope (SEM) ,WQL and surface area analyzer , it is showed by the result that the optimal Preparation Conditions to synthetize superfine cerium oxide comes down to this : Ortho charging ,stirring rate being 300r/min and aging time being 3h. Cerium oxide synthetized in this way appear to be lamellar granules , consistency of PSS being 0.5mol/L get the best result .But as time is limitied,we can’t take other Preparation Conditions into account ,which leads to the irregular shape of the granules ,thus further research is needed. 相关单词： charging style ：加料方式 aging time：陈化时间 scanning electron microscope:扫描电镜 WQL：粒度仪 surface area analyzer：比表面积仪 Ortho charging ：正加料法  |

A superfine cerium oxide was controllable template synthesized with polymer PSS as the template and cerium nitrate and ammonium hydrogen carbonate as starting materials. The optimum conditions for preparation was found through studying on the PSS's concentration, charging manner, and ageing time. The superfine compound was characterized by means of SEM, particle size analyzer, and specific surface area meter. The result showed that conditions for the the PSS template synthesis of superfine cerium oxide is as: 正加？, agitating at 300rpm, ageing for 3h. The cerium oxide obtained by this procedure are flaky particles, and the best result will be got when PSS's concentration is 0.5mol/L. However, further investigation should be carried out, due to the time limit, no sufficient conditions for preparation, and the irregular shaped particles. |
