Abstract:
Al2O3 is commonly present in, or introduced to, tetragonal zirconia polycrystal (TZP) ceramics as either an impurity or an additive during powder manufacture and/or subsequent processing, although its effects are not well understood. A study has been carried out into the effects of variously dispersed Al2O3 at the 0–1 wt.% level on the sintering characteristics, microstructure, phase composition, and mechanical properties of yttria stabilised, tetragonal zirconia polycrystal (Y-TZP). The results show that these levels of Al2O3 can enhance sintering at low temperatures, but can also cause exaggerated grain growth and reduction in sintered density for higher sintering temperatures, with corresponding changes in the mechanical properties.
