Description	The synthesis of nanocrystalline europium-titanate pyrochlore Eu2Ti2O7 by a generic sol gel approach is presented. The size of the formed nanocrystals was tailored from 20 nm to 100 nm. The nucleation process and the crystallization mechanism were studied. The activation energies of the crystallization process and crystal growth were calculated. It was found; from the calculated Avrami0s parameters; that the crystallization process starts by homogenous nucleation followed by three dimensional growth. The activation energies of the crystallization process were about 700 kJ mol 1. The energy of nanocrystal growth was 26.573.9 kJ mol 1. The results present fundamental information about the crystallization behavior of RE2Ti2O7 prepared by the condensation of titanium alkoxides with inorganic salts of rareearth elements.
