Abstract
The effect of directed laser treatment on the compacted binary mixtures Al2O3–Y2O3, Y2O3–TiO2, Al2O3–TiO2 and ternary mixtures Al2O3−Y2O3−TiO2 was investigated. It was shown that phase formation occurs within the framework of binary mixtures Al2O3–Y2O3, Y2O3–TiO2, Al2O3–TiO2 and is accompanied by the formation of Y3Al5O12, Y2Ti2O7 and Al2TiO5 compounds. The set of phases and microstructures of generated ceramics depend on Al2O3 content and TiO2/Y2O3 ratio in initial mixtures. Basing in the obtained results the tentative phase diagram for the Al2O3–Y2O3−TiO2 system was constructed.
