摘要：
The effect of additives complicating the formation and evolution of cracks in corundum ceramics in the course of temperature cycling is considered. It is established, that niobium oxide enhances the strength, while hollow corundum microspheres reduce the strength and enhance heat resistance. The combined introduction of the additives leads to decrease in the strength and heat resistance.
