Effect of microwave sintering on the properties of copper oxide doped alumina toughened zirconia (ATZ)
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...
