Abstract

The lowest activation temperature of a commercial vacuum getter reported so far in literature was about $400^{\circ}C$. Recently, $Ti_{0.3}Zr_{0.2}V_{0.5}$ alloy has been reported to exhibit the activation temperature lower than $200^{\circ}C$ when they are prepared as thin film. In this study, the alloy was prepared as bulk form and its activation temperature and hydrogen sorption properties were investigated in compliance with a standard method. The alloy powder was prepared by arc melting and subsequent HDH(Hydride-DeHydride) process. The activation temperature of the alloy was estimated from the ultimate pressure-temperature curve and located between $150^{\circ}C\;and\;200^{\circ}C$. The hydrogen sorption speed measured by an orifice method was 0.895 liter/sec which is comparable to thin film of same composition.
