The present work demonstrates that additions of lanthanum oxide can counter the negative grain boundary effects of relatively high silica contents in 8mol% yttria-stabilized zirconia (YSZ). This can be predicted by thermodynamic analysis, showing strong affinity between silica and lanthanum oxide at typical sintering temperatures. Microstructural analysis revealed the onset of La- and Si-rich precipitates,...
NiO/8YSZ (8mol% Y 2 O 3 -stabilized cubic ZrO 2 ) and NiO/3YTZP (3mol% Y 2 O 3 -stabilized tetragonal ZrO 2 ) composites with different NiO contents have been fabricated by a conventional route of mechanical mixing of NiO and zirconia powders and sintering at 1500°C for 10h in air. The resulting microstructures have been characterized by electron microscopy...
