dcterms:description
The influence of various dopants (500 ppm MgO and Y2O3;250 ppm ZrO2) on sintering of fine-grained alumina ceramics was evaluated by high-temperature dilatometry. The apparent activation energy of sintering was estimated with the help of Master Sintering Curve and a model proposedby Wang and Raj. The densification kinetics was controlled by at least two mechanisms operating at low (higher activation energy) and high (loweractivation energy) densities. Good agreement between the activation energies calculated with both models was observed for low as well as forhigh densities. The lowest value of activation energy exhibited undoped alumina; the addition of MgO resulted in slight increase of the activationenergy. Y2O3and ZrO2significantly inhibited the densification, which was reflected in the higher sintering activation energies. The low activationenergies in the final sintering step indicates the importance of proper choice of sintering temperature, namely in the two-step sintering process.
