Abstract
It is shown in the article how the clay and Y2O3 additions, and the temperature difference at range of 1000/20-1500/20 °C influence the crystal phase development, crystal sizes, elastic modulus, ultimate bending strength, linear correlation between elastic modulus and ultimate bend strength of ceramic samples, obtained in course of the mixture components conventional sintering at 1300 and 1500 °С. The most intensive development of the mullite phase and tetragonal ZrO2 crystallysation, and the related increasingof crystal size takes place in the samples obtained at 1300 °C and subjected the thermal shock at the temperature between 1400/20 и 1500/20 °С. Such samples have the largest values of ultimate bending strength and are characterized by implicit development of linear correlation between elastic modulus and ultimate bending strength. Ill. 5.
