Santos, M. de Andrade, J. Sampaio, A. da Luz, T. Ogasawara] TiO2-CeO2 oxides for application as ceramic pigments were synthesized by the Pechini method. In the present work the polymeric network of the pigment precursor was studied using thermal analysis. Results obtained using TG and DTA showed the occurrence of three main mass loss stages and profiles associated to the decomposition of the organic matter and crystallization. The kinetics of the degradation was evaluated by means of TG applying different heating rates. The activation energies (E a) and reaction order (n) for each stage were determined using Horowitz-Metzger, Coats-Redfern, Kissinger and Broido methods. Values of E a varying between 257-267 kJ mol-1 and n=0-1 were found. According to the kinetic analysis the decomposition reactions were diffusion controlled.
