| Summary: | The invention provides a process for producing vanadium alloy foil suitable as a membrane in a hydrogen-refining unit.
A vanadium alloy comprising 5 to 25% by weight of at least one selected from the group consisting of Ni, Co, Mo, Fe and Ag, 0.01 to 5% by weight of at least one selected from the group consisting of Ti, Zr and Y, and the balance being V is used. A melt of the vanadium alloy is prepared by use of a crucible
1
having slit
3
in the bottom, a roll
2
comprising a cylinder whose central axis is arranged to be parallel to the slit is rotated, the melt is jetted from the slit
3
to the roll surface
5
, the melt is jetted from the slit
3
is rapidly cooled, and the vanadium alloy solidified on the roll surface
5
is continuously exfolitated from the roll surface
5
to obtain the foil. |
