Research Abstract

At the phase transition around the 400K which was newly found for hafnium hydride, it turned out that the isotope separation by hydrogen absorption and desorption is difficult. On the other hand, it turned out by using the hydrogen desorption above 900K that desorption of hydrogen gas(H_2), deuterium gas(D_2), and hydrogen-deuterium gas(HD) was observed. It also turned out that a plate form of hafnium is good for hydrogen absorption and desorption.
