Conclusions
Comparative investigation of the crack resistance and thermal-shock resistance of aluminum oxide materials with a granular and with a layered-granular structure shows the advantages of using the latter in conditions of high-velocity heating and cooling. The breakdown of such a material is characterized by stages of acceleration and retardation of the dissemination of cracks, as a result of a change in its orientation in relation to the direction of the action of the maximum tensile stresses.
