  • Method for forming improved H.sub.2 -permselective oxide membranes using temporary carbon barriers
    Patent number: 5503873
    Abstract: A method of forming inorganic membranes which are highly selective to permeation of hydrogen by temporarily forming a carbon barrier in the pores of a porous substrate, followed by chemical deposition of SiO.sub.2, B.sub.2 O.sub.3, TiO.sub.2, Al.sub.2 O.sub.3 and mixtures thereof in the pores, followed by removal of the carbon barrier. It has been demonstrated that the permeation selective layers thusly formed by this invention have a five fold increase in permeance over such layers made by a similar method but without forming a temporary carbon barrier in the pores of the porous substrate, and removal of the carbon-barrier after establishment of the oxide membrane. Some suitable porous substrate are Vycor.TM. glass or Al.sub.2 O.sub.3.
