[en] Full text: Zinc titanates are highly versatile materials, and mentioned in many studies, among them the application as white pigments, catalytic adsorbents and photovoltaic cell electrodes. The polymer precursor method, hydrothermal and solid state reactions, are the most widely used methods in the synthesis of these compounds. In the present work, these oxides were synthesized in a solution of zinc acetate and titanium isopropoxide in ethyl alcohol using the microwave assisted solvothermal method. The powder obtained in the synthesis was subjected to a thermal treatment with four different temperatures for two hours and later characterized using X-ray diffraction, scanning electron microscopy, Raman spectroscopy and UV-visible spectroscopy. The results showed the formation of two cubic phases of titanates Zn₂TiO₄ and Zn₂Ti₃O₈ when the heat treatment temperature was 600°C and 700°C. When the temperature used in the heat treatment was 800°C, three phases were formed, the two cubic ones being added a rhombohedral ZnTiO₃ titanate. Raman spectroscopy showed active modes that corroborate with the results of XRD analysis. Band gap measurement using UVvisible spectroscopy showed an increase in energy as the heat treatment temperature increases, which may be linked with the formation of multiple phases of the zinc titanates.
