ABSTRACT:
The molding composition contains, in a flowable binder, from 20 to 50% by vol., based on the total volume of the molding composition, of a powder comprising one or more metal oxides and, if desired, metal carbides and/or metal nitrides which cannot be reduced using hydrogen, where at least 65% by vol. of the powder has a maximum particle size of 0.5 .mu.m and the remainder of the powder has a maximum particle size of 1 .mu.m, and at least 90% by vol. of the powder comprises metal oxides which can be reduced using hydrogen. The metal oxides which can be reduced using hydrogen are Fe.sub.2 O.sub.3, FeO, Fe.sub.3 O.sub.4, NiO, CoO, Co.sub.3 O.sub.4, CuO, Cu.sub.2 O, Ag.sub.2 O, Bi.sub.2 O.sub.3, WO.sub.3, MoO.sub.3, SnO, SnO.sub.2, CdO, PbO, Pb.sub.3 O.sub.4, PbO.sub.2 or Cr.sub.2 O.sub.3, or mixtures thereof.
