摘要
由于其良好的储放氧能力和热稳定性,以铈为主的铈锆氧化物在汽车尾气的处理中得到了越来越广泛的应用。文章通过对沉淀剂、沉淀方法等的研究,探索了实验室制备较大粒径稀土复合氧化物的优化条件。
The rare -earth -zirconium composite oxides which have high thermal stability and high storage of oxygen are getting more and more attention in the automotive exhaust cleaning field. We explored the opti- mal way to prepare the large grain of rare -earth composite oxide, though the selection of best precipitator, best way to deposition etc.
