Process for injection molding ceramic composition employing an agaroid gell-forming material to add green strength to a preform

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° C. and about 22. degree. C. and a gel consisting essentially of about 4 wt. % of the gel- forming material and water, of at least about 100 g/cm.sup.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 a gel. The preferred gel-forming material is an agaroid and the preferred molding process is injection molding.
