Resumo

In this work, spinels with the general formula Zn2-xCoxTiO4 were synthesized by the polymeric precursor method and thermally treated at 1,000 A degrees C. The powder precursors were characterized by TG/DTA. A decrease in the DTA peak temperature with the amount of zinc was observed. After the thermal treatment, the characterizations were performed by XRD, IR, colorimetry and UV/VIS spectroscopy. The XRD patterns of all the samples showed the presence of the spinel phase. Infrared spectroscopy showed the presence of ester complexes for Zn2TiO4 after thermal treatment at 500 A degrees C, which disappeared after cobalt addition, indicating that organic material elimination was favored.
