ABSTRACT:
A hydrogen diffusion diaphragm for selective separation of hydrogen from hydrogen-containing gaseous mixtures, which comprises a body of a titanium-alloy of more than 50 molar percent of nickel exhibiting a diffusion coefficient sufficient to allow permeation of the hydrogen through the diaphragm. The diaphragm is produced by mixing nickel and titanium in such proportions that the resultant mixture contains more than 50 molar percent of nickel, by forming the mixture into an alloy and by shaping the alloy into a diaphragm.
