Abstract
This paper describes the results of experiments on the interaction of hydrogen isotopes with lithium ceramics of different grades. The studies were carried out in two stages: a cycle of work on saturation of samples in a deuterium medium was conducted at a facility for studying the interaction of gases with materials (CorrSiC’a)) based on an industrial highvacuum tube furnace GSL-1600, at temperatures of 300 °C, 500 °C, 700 °C; hermal desorption (TDS) experiments at a facility, where the sample is heated by a non-contact method (induction heating) at a rate of 2 K/s and 10 K/s, at a pressure of residual gases in the installation chamber ~10−4 Pa. The values of the activation energy of deuterium gas release from lithium ceramics of different grades are obtained.
