Abstract

A carbon electrode, in particular a graphite electrode for producing steel which can be used for electric arc melting furnaces of conventional design. The electrode comprises a metal-containing protective layer, and fusion of the contact jaws of the electrode holder with the metal-containing protective layer is avoided by covering at least part of the electrode surface by a graphite-containing material.
