Structural and Electrical Properties of Sintered Barium-Zinc-Titanate Ceramics

The aim of this work was an investigation of structural and electrical properties of sintered barium-zinc-titanate ceramics. Mixtures of BaCO(3), ZnO and TiO(2) were mechanically activated in a planetary ball mill up to 80 minutes and sintered isothermally in air for 120 minutes at 1300 degrees C. The phase composition in the BaCO(3)-ZnO-TiO(2) system after milling and sintering was analyzed using the XRD method. The existence of pure barium-zinc-titanate has been registered. Microstructure analyses were performed using SEM. The results of electric resistivity, capacitance and loss tangent of the sintered samples were correlated with the XRD and SEM results.12th Annual YUCOMAT Conference, Sep 06-10, 2010, Herceg Novi, Montenegr
