本文主要探讨在草酸沉淀法制备氧化铈的过程中,通过调节pH、采用不同的沉淀剂和添加分散剂使中间产物草酸铵铈充分分散,最后经焙烧得到分散良好的小颗粒氧化铈。
The influence of pH,precipitant and dispersant is investigated for the preparation of CeNH4(C2O4)2*H2O. Well di spersed precipitation of Ce NH4(C2O4)2*H2O is obtained by controlling above conditions.Finally well dispersed cerium oxide is prepared by thermal dec omposition of CeNH4(C2O4)2*H2O.
