1. Ni catalysts supported by zirconia, which have high activity for the reaction for methanation of carbon dioxide with hydrogen, were prepared from amorphous Ni-Zr alloys, and evaluated their activity in relation with alloy composition, reaction temperature. It was found that their activity was highest when they have prepared from Ni-Zr alloys containing Zr from 40 to 50at%Zr. The origin of the alloy composition dependence was explained by the alloy composition dependence of dispersion of metallic Ni on the catalyst surface, turnover number, and the relative concentration of tetragonal zirconia in the support. On the base of the above results, catalysts with higher activity were prepared by addition of a certain amount of Sm which caused stabilization of tetragonal phase of zirconia and increase of Ni dispersion on zirconia.2. Non-equilibrium Nb-W and Nb-Mn alloys were prepared by sputtering method. They showed amorphous structure within the composition range of 20-50at%W and 26-75at% … More Mn, respectively. Their corrosion resistance and surface compositions were evaluated by electrochemical measurements and photoelectron spectroscopy.3. Co-20at%Al alloy prepared by sputtering method was a non-equilibrium metallic compound with CsCl-type structure. When alloy films were prepared by reactive sputtering in NィイD22ィエD2 and OィイD22ィエD2 containing atmosphere, they showed ferromagnetic property with high performance even at high frequency region. It was clarified that they were composed of nano-particles of Co surrounded by insulating AlN and AlィイD22ィエD2OィイD23ィエD2, respectively.4. Sr-Bi-Ta oxides prepared by sol-gel method followed by annealing at low temperatures showed no ferroelectric properties. But they become ferroelectric substance at high temperature annealing. Their performance was, however, dependent on annealing temperature and atmosphere during annealing. It was made clear that deviation of surface composition from stoichiometry and existence of metallic Bi were harmful to ferroelectric performance. Less
