The effect of the addition of 2–8 wt% Y₂O₃ on the structural evolution, microstructural development and mechanical properties of 0.50Al₂O₃–0.50ZrO₂ ceramics was determined. The present study has been performed to understand and control the densification behaviour with optimal Y₂O₃ addition. The phase composition of the samples was characterized by the X-ray diffraction (XRD) technique. Refinement of the lattice parameters using Rietveld analysis revealed the quantitative phases of the alumina–zirconia–yttria composites.
