Abstract

The invention relates to agents for the desulfurization of metal melts, especially of steel and crude iron melts, based on mixtures of CaC.sub.2 /CaO crystals produced in the fused mass. A portion of the CaO in the crystal mixture is hydrated to form Ca(OH).sub.2. A process for the manufacture of these agents is also described.
