Hydrogen absorption experiments were carried out using the zirconium (Zr) and titanium (Ti) in the form of a metal sponge, strip and rod to investigate the characteristics of hydrogen absorption The Zr and Ti sponges showed a high hydrogen absorption capacity inspite of a low reaction temperature. The H/M, which indicates the capacity of hydrogen absorption, was measured at 20 for the Zr ansi Ti sponges under experiment;tl condition of 25 ℃. However, in the case of the Zr and Ti strip and rod, the hydrogen absorption capacity was very low at 25 ℃. But, the capacity of hydrogen absorption increased with an increase in the reaction temperature. When the Ti strip was not activated, the H/M ratio was measured at 0.58. But, when the Ti strip was once and twice activated at 800 ℃ for 1 h, the H/M ratio increased to 1.6 and 1.83, respectively. A pulverizing phenomenon during the metal hydriding was observed in both the Zr/Ti strip and the Zr/Ti rod. However, this pulverizing phenomenon was not observed in the Zr and Ti sponges because of their high surface area.
