Abstract:

La-Mo series complex oxide ultrafine particles have been prepared successfully by the sol-gel method at low temperature. The influence of preparation conditions and thermal treatment conditions on the morphology and the structure of the oxide particles has been studied by using XRD, DTA-TG, TEM, FT-IR and BET surface area measurement methods. For the preparation of the well-distributed La-Mo series complex oxide ultrafine particles with the size in the range of 40-80nm, the optimum conditions are:
ncitrie/nLa+Mo=0.3, pH≤1.5, t≤500℃.
