Microstructure of Composite Derived by Oxidation of Amorphous Zr₆₅Pd₃₅ Alloy and the Interaction with Hydrogen

抄録

The microstructure of composite derived from amorphous Zr₆₅Pd₃₅ alloy and its hydrogen treatment behavior were examined. XRD, SEM and Raman spectroscopy revealed that the composite containing ZrO₂, metallic Pd and PdO was formed by heat treatment of amorphous alloy. The Zr₆₅Pd₃₅ alloy heated at 280 °C in air, followed by heat treatment in hydrogen, changed to the composite in which Pd precipitates with less than 100 nm in diameter were embedded in ZrO₂ matrix. The unique property of rapid hydrogen absorb and release in a composite derived from alloy was found.
