The influence of MgO and La2O3 on the fast sintering of mullite was evaluated in this work. High-purity mullite was doped with MgO and La2O3, conventionally sintered, fast sintered, and microwave-sintered in rapid sintering cycles. The results showed that MgO and La2O3 strongly affected the densification of fast sintered samples; and only doped bodies reached high densities when fast sintered. However, the densification behavior of doped samples was dependent on the amount of sintering aids. MgO doped samples presented better densification behavior than La2O3 doped samples. Microwave-processed samples required a balance between power, time and amount of additives to obtain highly dense and homogenous microstructures. (AU) | |
