Abstract
A carrier material to be used as a placeholder for structuring workpieces having at least one vacuity is disclosed, said carrier material comprising at least two metal powders Mel and Mell, the standard electrode potentials of which are different at room temperature, which can be produced by a method compacting the powders, as well as a method for producing same.

1-19. (canceled)
A carrier material usable as a placeholder for structuring at least one vacuity of a workpiece, comprising:
- a compacted corrodible material having at least two metal components, Mel and Mell, wherein the standard electrode potential of Mell is smaller than that of Mel under reaction conditions.
A method for producing a workpiece having a body with at least one vacuity comprising:
- forming the at least one vacuity with a compacted carrier material comprising two metal powers each having a different standard electrode potential;
- and
- removing the carrier material after completion of the body, without damaging the body, by contacting the carrier material with an aqueous medium and rinsing away a resulting suspension of the carrier material and the aqueous medium.
Use of a mixture of two metal components, Mel and Mell, wherein the standard electrode potential of Mell is smaller than that of Mel under reaction conditions, for producing a lost mould using a compacting technique.
