Abstract

Amorphous metal alloys have the formula EQU M.sup.1.sub.a M.sup.2.sub.b M.sup.3.sub.c where PA0 M.sup.1 is Fe, Co, Ni, Pd and combination thereof; PA0 M.sup.2 is Ti, Zr, Hf, V, Nb, Ta and combination thereof; PA0 M.sup.3 is Rh, Os, Ir, Pt and combinations thereof; PA0 a ranges from about 0 to 60; PA0 b ranges from about 10 to 70; and PA0 c ranges from about 5 to 70, with the proviso that a+b+c=100. These alloys have utility as anodes in electrolytic processes and a process for the generation of halogens from halide-containing solutions includes a step of conducting electrolysis of the solutions in an electrolytic cell having an amorphous metal alloy anode of the formula EQU M.sup.1.sub.a M.sup.2.sub.b M.sup.3.sub.c.
