Phase transformations in the samples of composite ceramic in the system ZrO2(Y)–Al2O3, which are distinguished by the value of the porosity and the content of yttrium as a stabilizing impurity, are studied as a function of their storage time at room temperature. It is shown that a reduction of the molar content of yttrium oxide in the zirconium phase of the porous composite results in a sharp acceleration of the its low-temperature aging. The phase transitions are studied by means of dilatometry in an aged composite in the temperature range 30 – 600°C.
