Starting mixtures of BaCO3, ZnO, and TiO2 powders are mechanically activated in a planetary ball mill for various periods of time. The powders obtained are sintered isothermally at 1100°C for 120 min. Non-isothermal sintering process is followed by measurements with a sensitive dilatometer, as well. Results of microstructure characterization using SEM analyses along with DTA analyses are provided. These results are correlated with the values of electric resistivity, capacitance, and loss tangent of the samples, and it is found that with increasing milling time, the increase in values of electrical properties is noticed.
