Raman spectroscopy was used to determine the phase composition of the samples solidified from the Al2O3-TiO2 powder. The resulting beta-Al2TiO5-Al6Ti2O13, beta-Al2TiO5-Al2O3 single crystals were probed with micro hardness assays, scratch test analyses, atomic force microscopy (AFM), scanning electron microscopy (SEM), thermal expansion and four-point bending tests. It was observed that the alumina-tialite single crystal retained a composition of Al2O3-TiO2 containing 60% Al2O3 by weight and displayed optimum properties.eninfo:eu-repo/semantics/openAccessAluminaAlumina-tialiteSingle crystalMicrostructureEffect of TiO2 doping on microstructural properties of Al2O3-based single crystal ceramicsArticle1212125Q3WOS:0002885242000052-s2.0-79961009490Q3
