Article

The development of a reliable system for protecting beryllium from oxidation and the sublimation of its toxic oxides during heating at high temperatures is examined. The results of investigations of the oxidation kinetics of beryllium with no coating, with a passive film, and with a composite coating at heating temperatures to 900°C in 50 h are presented. It is shown that a composite coating consisting of a passivating layer and a heat-resistant coating based on the system SiO2–B2O3–R2O is effective.
