Abstrakt:	The effect of Al2O3 weight content on the stability of the phase composition and strength of ceramic in the system Al2O3-3Y-ZrO2 prepared by a commercial technology was determined. It was shown that the introduction of aluminum oxide has a positive effect on the stability of the tetragonal phase of zirconium dioxide during accelerated aging. At the same time increasing the mass content of aluminum oxide from 15 to 80% does not significantly change the ratio t-ZrO2/m-ZrO2. It was observed that the strength of all materials containing aluminum oxide increases after aging for 5 h. [ABSTRACT FROM AUTHOR]
