Abstract: A method and composition for treating molten metals and alloys of the iron group with a reactive metal to produce nodular iron. The composition is in the form of a self-contained body formed by compressing a mechanical mixture of particles of a reactive metal, particles of synthetic graphite and a binder with the particles of synthetic graphite surrounding and protecting the particles of reactive metal so that there is controlled release of the reactive metal into the molten metal upon submerging the self-contained body into the molten metal.
