ABSTRACT:
A batch, in particular for the production of a refractory shaped body, includes at least one refractory metal oxide component and a synthetic resin component as a binder, and a graphitizing auxiliary for producing crystalline graphite carbon from the resin. The graphitizing auxiliary originates from a group consisting of reducible organic compounds of transition elements and/or a group of active organic or inorganic metal compounds or metals, such as resin-soluble metal salts, chemically precipitated or micronized metal oxides or metals. The graphitizing auxiliary is available in molecular form over the time and/or temperature range of conversion of the synthetic resin into carbon (carbonization).
