In this article the influence of mechanical activation on sintering process of bariumstrontium-titanate ceramics has been investigated. Both non-activated and mixtures treated in a planetary ball mill for 5, 10, 20, 40, 80 and 120 minutes were sintered at 1100-1400°C for 2 hours in presence of air atmosphere. The influence of mechanical activation on phase composition and crystal structure has been analyzed by XRD, while the effect of activation and sintering process on microstructure was investigated by scanning electron microscopy. It has been established that temperature of 1100°C was too low to induce final sintering stage for this system. Electrical measurements have been conducted for the densest ceramics sintered at 1400°C for 2 hours. [Projekat Ministarstva nauke Republike Srbije, br. OI172057]
