Abstract (en)
[origin: EP0451467A1] Method of moulding any desired metallic and/or ceramic component, in which a dry powder is poured in bulk form into a ceramic mould which elastically and plastically yields or cracks or breaks under the influence of shrinkage stresses during sintering and is sintered. Variants for the mould: thin yielding shells composed of Al2O3, SiO2, MgO; special glass which cracks in grid fashion; mould with predetermined fracture points (9), ceramic shell which breaks up into fragments; flexible green ceramic sheet; green ceramic compound which shrinks during sintering. <IMAGE>
