METHOD FOR PRODUCING ALLOY FOR HYDROGEN-PERMEABLE MEMBRANE

Document Type and Number:

Japanese Patent JP2003010659

Kind Code:

A

Abstract:

To produce a hydrogen-permeable membrane alloy having the characteristics of a hydrogen permeable membrane and to obtain a whole alloy free from defects such as blowholes.

A method is provided for producing a hydrogen-permeable alloy from an alloy material having a composition of 3-15 atom.% at least one of Ce, Sm, Tb, Dy, Ho, Er, and Yb, and the balance Pd with inevitable impurities or from an alloy material having a composition of 0-20 atom.% at least one of Ag, AU, and Cu, 3-15 atom.% at least one of Ce, Sm, Tb, Dy, Ho, Er, and Yb, and the balance Pd with inevitable impurities. It is possible to obtain a whole ingot free from defects such as blowholes and low in a content of a dissolved gaseous component, to simplify a production process, to reduce the cost, and to obtain a hydrogen-permeable membrane alloy at a high efficiency.
