Composition for use in oxygen permeable membranes. The present invention relates to a composition for use in oxygen permeable membranes, of the formula : al-x-y-zbxc and dzor, where a is an alloy of the "mischmetal" type comprising at least two rare earth metals; and where b, c and d are metals selected from a group consisting of co, fe, cr, mo, w, re, pd, mn, mg, zr, th, pr, tb, eu and er, being 0.01 <= x <= 0.2; 0 <= and <= 0.2; and 0 <= z <= 0.2. Likewise, it relates to a process for obtaining said composition and its use for the shaping of oxygen permeable membranes. (Machine-translation by Google Translate, not legally binding)
