Ti0.3Zr0.2V0.5 합금게터의 활성화 및 수소흡수특성
Activation and Hydrogen Sorption Characteristics of a Ti0.3Zr0.2V0.5 Alloy Getter
E-mail:
The lowest activation temperature of a commercial vacuum getter reported so far in literature was about . Recently, alloy has been reported to exhibit the activation temperature lower than 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 . The hydrogen sorption speed measured by an orifice method was 0.895 liter/sec which is comparable to thin film of same composition
