U ovom radu proučavan je uticaj mehaničke aktivacije na proces sinterovanja barijum-stroncijum-titanatne keramike. Neaktivirana i mehanički akativirane smeše (u temperatuskom intervalu 5 - 120 minuta) u visoko- energetskom planetarnom mlinu sinterovane su na 1100 - 1400°C dva sata u atmosferi vazduha. Uticaj mehaničke aktivacije na fazni sastav i kristalnu strukturu je analiziran pomoću rendgenske difrakcije, dok je defekat aktivacije i proces sinterovanja na mikrostrukturu ispitivan skenirajućom elektronskom mikroskopijom. Utvrđeno je da je temperatura od 1100°C bila isuviše niska da se podstakne završna faza sinterovanja za ovaj sistem. Električna merenja su sprovedena za najgušće keramike sinterovane na 1400°C dva sata.
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.
