Wässerige Zusammensetzungen zum Spritzgiessen bestehend aus einem gelbildendem Material und aus keramischen und/oder metallischen Pulvern.

摘要

A process for shaping parts from metallic and/or ceramic powders is disclosed. The process comprises the steps of forming a mixture comprising metal and/or ceramic powders, a gel-forming material having a gel strength, measured at a temperature between 0 DEG C and about 22 DEG C, and from a gel consisting essentially of about 4 wt.% of the gel-forming material and water, of at least about l00 g/cm<2>, and a gel-forming material solvent, and molding the mixture at a temperature sufficient to produce a self-supporting article comprising the powder and the gel. The preferred gel-forming material is an agaroid and the preferred molding process is injection molding.
