Sintering of mechanically activated magnesium-titanate and barium-zinc-titanate ceramics

The effect of mechanical activation on the sintering process of magnesium titanate and barium zinc titanate ceramics was studied. Both nonactivated and mixtures treated in a planetary ball mill for 80 min were sintered at 1100 C and 1300 C. The influence of mechanical activation on the phase composi...

Summary:The effect of mechanical activation on the sintering process of magnesium titanate and barium zinc titanate ceramics was studied. Both nonactivated and mixtures treated in a planetary ball mill for 80 min were sintered at 1100 C and 1300 C. The influence of mechanical activation on the phase composition and crystal structure was analysed by XRD, and the effect of activation and sintering on the microstructure was investigated by SEM. A temperature of 1100 C was too low to induce the final sintering stage for both systems. It was concluded that barium zinc titanate ceramics exhibited better sinterability than magnesium titanate ceramics.
