Abstract

A method for sintering metallic and/or non-oxide components includes completely encapsulating, in a metal halide salt, a green body comprising at least one metallic and/or non-oxide powder, and compressing the encapsulated green body so as to be gastight. The method further includes heating, together with a metal halide salt in the presence of oxygen up to sintering temperatures, the compressed, encapsulated green body. The method additionally includes at least partially dissolving, after cooling, the metal halide salt in a liquid so that the sintered component can be removed.
