An alloy of formula: Ti30+x Ru15+y Fe25+z O30+t Mu wherein M represents at least one metal selected from the group consisting of chromium, manganese, vanadium, tungsten, antimony, platinum and lead; x is an integer ranging between - 30 and + 50; y is an integer ranging between - 10 and + 35; z is an integer ranging between - 25 and + 70; t is an integer ranging between - 28 and + 10; and u is an integer ranging between 0 and + 50; x, y, z, t and u being selected so that: x + y + z + t + u = 0. This alloy, especially when it has a nanocrystalline structure, is useful for the manufacture of cathodes for the electrochemical synthesis of sodium chlorate. These cathodes have an over-potential of hydrogen lower than the one of the soft-steel cathodes presently in use. |
