| Abstract: | A new type of non evaporable getter with high sorption capacity for hydrogen was investigated. The material made by sintering in vacuum consists of Zr, Zr Al16 and Zr V Fe alloy. The inspiration capacity for hydrogen, microstructure and phase composition were characterized by SEM and XRD analysis. The results show that this getter has better sorption capacity for hydrogen than other analogous products and offers excellent sorption properties at both low and high temperature activation conditions. |
