Abstract
Abstract Amorphous metal alloys have the formula M1aM2bM3c where M1 is Fe, Co, Ni, Pd and combination thereof; M2 is Ti, Zr, Hf, V, Nb, Ta and combination thereof; M3 is Rh, Os, Ir, Pt and combinations thereof; a ranges from about 0 to 60; b ranges from about 10 to 70; and 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 M1aM2bM3c.
