Role of MgO nanoparticles on zirconia-toughened alumina-5 wt-% CeO2 ceramics mechanical properties

The poor hardness of zirconia-toughened alumina (ZTA) with 5 wt-% CeO2 (ZTA5CeO2) ceramic has limited its applications as a cutting insert. Therefore, in this work, the possibility of MgO nanoparticles (20 nm) as reinforcement to ZTA5CeO2 ceramics was investigated. Mgo nanoparticles with different w...
