The microstructural development of 3 and 8 mol% yttria-zirconia ceramics during microwave sintering was studied and compared to conventionally heated samples. Microwave heating enhanced the densificaiton processes occurring during constant-rate heating for both materials. No change was found in the grain size-density relationship for the 8 mol% yttria-zirconia. However, a small, but statistically significant shift favouring densification was found for the 3 mol% yttria-zirconia.
