Abstract
Process for shaping any desired metallic and/or ceramic component, in which a dry powder is filled loosely into a ceramic mold, which elastically/plastically yields or cracks and breaks under the influence of shrinkage stresses during sintering, and is sintered. Variants for the mold: thin, resilient shells made of Al.sub.2 O.sub.3, SiO.sub.2 or MgO; special glass which cracks in a network-like manner; a mold having predetermined breaking points, ceramic shell disintegrating into fragments; flexible green ceramic sheeting; green ceramic composition with shrinkage during sintering.
