This study investigated the effect of copper oxide addition on the alumina toughened zirconia composite ceramic using microwave sintering. CuO amounts (0.05�1 wt%) were examined at sintering temperatures (1250�1500 �C). Investigations covered hardness, toughness, phase stability, microstructure, and...
