This paper reports an investigation on the impact of in-situ formation of CaAl12O19 (hibonite) on the microstructure and mechanical properties of zirconia-toughened-alumina (ZTA). Various amounts of CaCO3 (0–13 wt%) were added to ZTA to form CaAl12O19. Samples were sintered at 800 °C for 4 h to obta...
