Effect of synthesized yttrium aluminum garnet (YAG) additives on the physical and the mechanical properties of zirconia toughened alumina (ZTA) composites
Yttrium aluminium garnet (YAG) nano powder was synthesised from yttria powder and aluminium isopropoxide via the sol-gel method and then calcined at 1500°C for 2 hours to obtain a pure YAG phase. Zirconia-toughened alumina (ZTA) composites containing 15% zirconia were mechanically mixed, then 10, 20 and 30 wt.% nano-sy...
