Results are provided for thermal cycling tests of a number of highly refractory products. It is shown that periclase products from fuzed powders coated with ZrO2 are the most resistant to cyclic variable thermal loads. The structure of corundum products in the process of thermal cycling tests deteriorates significantly due to recrystallization and the formation of new phases. In order to organize the lining and test unit heat exchange fittings operating under conditions of variable loads in pulsed piston units objects made from fuzed periclase powders modified with ZrO2 are recommended.
