Title:
PD BASE AMORPHOUS ALLOY FOR HYDROGEN SEPARATING AND REFINING MEMBRANE MATERIAL
Document Type and Number:
Japanese Patent JPS59205434
Kind Code:
A
Abstract:
PURPOSE: To provide the titled alloy having excellent properties wherein hydrogen permeability is high and the generation of a β hydride phase is not recognized, by containing Si in a Pd base alloy such as Pd-Ag to make the same amorphous.
CONSTITUTION: An alloy consisting of, on an atomic % basis, 9W30% of Si, 20% or less of X (one or more of Ag, Au, Cu, Ni and/or Fe) and the remainder of Pd is processed by an ultra-quenching method to obtain an amorphous Pd-Si-X alloy foil. This alloy foil is high in hydrogen permeability and generates no deterioration in material quality with the formation and disappearance of an α-phase/β-phase hydride phase as absorved in a crystalline Pd-alloy.
