Abstract: La2M2O7(M=Ti, Zr)powders have been hydrothermally synthesized at lower temperature from the double oxides xerogels by using KOHas mineralizer. The effects of some factors such as KOHconcentration, reaction temperature and time are investigated. Further details are given through XRD, TEM, IRand other techniques. The moderate conditions give the excellent ceramics powders: the resulting particles with a single mode of size distribution present a low agglomeration.

Key words: Low temperature hydrothermal synthesis, La2Ti2O7, La2Zr2O7, Polycrystalline powders
