Preparation of High-Surface Area Nano-CeO2 by Template-Assisted Precipitation Method He Mai1,Luo Mengfei1,Wang Yuejuan1,Fang Ping1,Ma Jingmeng1 (1.Zhejiang Key Laboratory for Reactive Chemistry on Solid Surfaces, Institute of Physical Chemistry, Zhejiang Normal University, Jinhua 321004, China) Abstract:The high-surface area nano-CeO2 was prepared by Ce(NO3)3 by precipitation method......
during homogenization. Furthermore, the Ce addition introduces changes in the precipitation process and consequently in the age-hardening behavior of the alloy. Microstructural measurements reveal that the addition of Ce promotes the precipitation of η' phase, but it also partly retards the precipitation of GP zones. The density of precipitates decreases in a certain degree and rod-like η......
