This article reported result of the synthesis nano CeO2 by combustion method. The process of the synthesize is prepared from the first substance (NH4)2Ce(NO3)6, glyxin and NH4NO3. Obtained CeO2 was examined by the method of X-ray diffraction (XRD), thermal gravimetry and differential thermal analysis, scaninng electron microscopy (SEM) and transmission electron mictron microscope, specsific surface area analysis by Brunauer-Emmet-Teller (BET) method. Obtained CeO2 has particle size 28.6 nm and surface area 18.25 m2/g.
