摘要： The process for the producing improved shaped sintered articles by first shaping a) a mixture of a ceramic or metallic powder or mixtures thereof with a moldable thermoplastic composition containing b) a thermoplastic polyoxymethylene binder and c) a second moldable and essentially inert thermoplastic polymer having a melting point between 90.degree. and 220.degree. C., such as a polyether of bisphenol A and an aliphatic diol. The binder is then removed from the shaped article by exposure to a gaseous acid-containing atmosphere, preferably below its softening temperature, while the second inert thermoplastic polymer is retained as a source of elemental carbon in which the ceramic or metallic powder is finely dispersed. This retained polymer is then pyrolyzed under an inert gas at elevated temperatures of at least 600.degree. C. for conversion to a finely dispersed elemental carbon. The resulting pyrolyzed preformed product is then sintered to obtain the desired high density ceramic and/or metallic article as the final product in which elemental carbon is uniformly and finely distributed. The process provides a simpler and more easily controlled method of incorporating elemental carbon into the ceramic/metallic shaped and sintered product while also carefully controlling the initial shaping step to prevent any formaldehyde induced crosslinking in the thermoplastic binder composition.

摘要： The preferred sintered parts made of oxygen-sensitive, non-reducible powders and their production by injection-molding are distinguished by the powders used being freed of their oxide layer by attritor milling in a water-free organic solvent, in the presence or absence of an additional reductant, the oxide particles being removed if necessary by filtration or screening in the presence of the organic solvent, the oxide-free powder being mixed as suspension with a polyacetal as binder under a protective gas, the organic solvent being distilled off, the mixture of powder and polyacetal being heated above the melting point of the polyacetal and being compounded to give a homogeneous composition, the granular material thus obtained being processed in an injection-molding machine made inert with argon to give shaped bodies, the shaped bodies being freed of binder under the action of oxalic acid in a closed ceramic container which nevertheless allows pressure equilibration under protective gas at atmospheric pressure or reduced pressure, the shaped bodies being, after binder removal, transferred in their container without contact with air into a sintering furnace and being sintered therein according to the prior art.
