摘要：

In this study, ultrafine La2Mo2O9 powders have been successfully prepared by a novel sol-gel combustion route using a unique combination of citric add. A range of analyzing techniques including XRD, TG-DSC and BET were employed to characterize the experimental powders. From the result of XRD patterns, we found that well crystalline cubic structure La2Mo2O9 was obtained by calcining the precursor gel at 600 C for 2 h. The as-synthesized powders have an average crystallite size of 30 nm.It has also powders modiced by sot-gel combustion method have fine sinterability, it can be sintered close to theoretical density at 950 degrees C for 4 h.
