Paper Title:
Preparation of La2Ce2O7 Nano-Powders by Molten Salts Method
  Abstract

La2Ce2O7 nano-powders with cubic fluorite structure have been firstly prepared by Molten Salts method. These nano-powders were prepared at relatively low temperatures(800°C and 900 °C) at different time, using La(NO3)3•6H2O and La(NO3)3•6H2O as raw materials, as well as K2SO4 (anhydrous) and Na2SO4 (anhydrous) as molten salts and dispersant. XRD, SEM were used to characterize the composition, morphology and size of prepared products. The procedure is facile and suitable for the synthesis of the La2Ce2O7 nano-particles and it will be an excellent method for preparation of other pyrochlore type of rare earth zirconate (Re2Zr2O7, Re=rare earth).
