Ferrophosphorus composition having improved conductivity and passivation resistance

A ferrophosphorus composition with improved conductivity and passivation resistance is prepared by treating ferrophosphorus particles with an aqueous solution containing a dilute mineral acid and ions of chromium and a metal selected from the group consisting of zinc, strontium, calcium, barium, lea...
