Studies are shown that tantalum and niobium have different kinetics of hydrogen uptake. Tantalum, in contrast to niobium, is able absorb actively hydrogen at room temperature, reaching a hydrogen capacity at the level of TaN1.9. Active absorption of hydrogen by niobium is observed only at heating to temperatures of 400–500°C, reaching the hydrogen capacity of NbH1.23. The kinetics of hydrogen evolution from both hydrogen-saturated metals is similar, the process takes place at room temperature, but in different pressure conditions. [ABSTRACT FROM AUTHOR] |
