Abstract
For the manufacture of shaped parts ( ) from ceramics, for example for dental-technical purposes, first of all a powdery ceramic raw material is compressed to form a ceramic green compact ( ). The inner contour and/or the outer contour of the shaped parts ( ) is then prepared by machining the ceramic green compact ( ) by means of eroding methods, with the ceramic green compact ( ) being embedded into a workpiece receiver ( ) before the Machining by means of an embedding mass ( ) which neither damages nor reacts chemically with the ceramic green compact ( ). Subsequently, the machined ceramic green compact ( ) is sintered to form a high-strength ceramic shaped part. A ceramic material which is almost shrinkage-free during sintering is preferably used.
