Phase diagram of the Y2O3-AlN system was calculated. Liquidus surface of the Al2O3-Y2O3-AlN system was constructed and compared with experimental results on primary crystallisation fields. Calculated temperatures of invariant reactions were in agreement with DTA results. Vertical sections of the Al2O3-Y2O3-AlN system were calculated and compared with experimental data.enaluminaaluminium nitrideCALPHAD methodphase diagramYttria620666620journal article
