Verfahren zur Herstellung eines Silizium enthaltenden nichtoxidischen Keramikformkörpers oder einer solchen Schicht

摘要

Producing a silicon-containing non-oxide ceramic material comprises subjecting a green body or layer, formed from a homogeneous powder of a non-oxidic silicon compound or pure silicon, to heat treatment at /- 800 deg C in an oxidising atmosphere and/or to heat input from a deflected laser beam. Also claimed is the production of an article by layer-wise selective laser sintering of the above material.
