| Popis: | The main objective of the proposed work is to investigate the structural properties of zinc titanates ceramics obtained by solid state reaction. The powders of composition (98 mol% ZnO + 2 mol% TiO2) were mechanically milled for 3 h in high energy planetary ball mill under argon atmosphere. After, the ball milled powders were calcined at 900°C for 2 h, pressed into pellets and then sintered for 4 h at 1100°C in air. The microstructural transformations were characterized by X-ray diffraction, Fourier transform infrared spectroscopy (FT-IR) and Raman scattering spectroscopy. The X-ray results exhibit a composite structure where about a small amount of rutile nanograins are dispersed into the ZnO matrix and a formation of a cubic inverse spinel Zn2TiO4. Raman and FTIR results confirm the multiphase character of the sintered pellets.The main objective of the proposed work is to investigate the structural properties of zinc titanates ceramics obtained by solid state reaction.
