In this article the influence of mechanical activation on sintering process
of magnesium-titanate and barium-zinc-titanate ceramics has been
investigated. Both nonactivated and mixtures treated in planetary ball mill
for 80 minutes were sintered at 1100ºC and 1300ºC. 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 1100ºC was to low to induce final sintering
stage for both systems. Moreover, we concluded that barium-zinc-titanate
ceramics exhibited better sinterability than magnesium-titanate ceramics.
