This paper shows the results of mechanical tests in a wide temperature range of reactor graphite and beryllium oxide. It is established that the compressive strength of graphite with increasing temperature test up to 1000 °C increases by ~10 %, while the fragile nature of the destruction is preserved. An increase in the test temperature leads to a sharp decrease in the strength properties of BeO by ~10 times. As shown by bending tests with increasing temperature, the destruction mechanism changes from brittle to brittle-viscous.
