Synthesis and Characterization of Zirconia-Alumina Ceramics Doped Niobium Oxide

Abstract:

Pure 8 mol% yttria stabilized zirconia (YSZ) and alumina with 1:4 to form ZTA sample and niobium oxide (Nb₂O₅) as dopant was added to the ZTA system. The samples were sintered at 1650 °C for 2h. The effect of niobium oxide addition as dopant in the ZTA ceramics sample were investigated. It is found that addition of niobium oxide up to 5wt.% had a positive effect on the microstructure and hardness of the ZTA ceramics sample which improve the mechanical properties of the ceramics samples.
