Abstract
An alloy of formula: EQU Ti.sub.30+x Ru.sub.15+y Fe.sub.25+z O.sub.30+t M.sub.u wherein M represent 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 cathodes for the electro-chemical synthesis of sodium chlorate. These cathodes have an over-potential of hydrogen lower than the one of the soft-steel cathodes presently in use.
