Abstract (en)
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>
Abstract (de)
Verfahren zur Formgebung eines beliebigen metallischen und/oder keramischen Bauteils, wobei ein trockenes Pulver lose in eine unter dem Einfluss von Schrumpfspannungen beim Sintern elastisch-plastisch nachgiebige oder reissende und brechende keramische Form eingefüllt und gesintert wird. Varianten für die Form: dünne nachgiebige Schalen aus Al2O3, SiO2, MgO; netzartig reissendes Spezialglas; Form mit Sollbruchstellen (9), in Bruchstücke zerfallende Keramikschale; flexible grüne Keramikfolie; grüne Keramikmasse mit Schwindung beim Sintern. <IMAGE>
