Outline of Final Research Achievements |
Be2Zr compounds have been successfully fabricated by a homogenization treatment of the mixed powders with stoichiometric value of Be2Zr under a controlled gas glove box. As a result of hydrogen storage capacity measurement by pressure of 13 MPa, hydrogen amount reached to 0.41%. Due to surface oxide layer, however, it was clear that the hydrogen capacity deteriorated. In order to improve this capacity, Co partially added to Be2Zr to replace to some of Zr, such as Be2Zr0.9Co0.1 and BeZr0.7Co0.3. As Co amount increased, Co2Zr and CoZr compounds increased. By these formations, accordingly, it was thought that hydrogen capacity obviously deteriorated.
