Abstract
The invention relates to a method for forming a green article for subsequent sintering or infiltration. This method includes providing a mold having an internal cavity that outlines the shape of the article, introducing metal or ceramic particles into the mold in an amount sufficient to provide the article in a desired size, adding a solution comprising an organic fluxing agent onto the particles with the solution carrying the organic fluxing agent into interstices between the particles, and freezing the solution to form a solid green article. The invention also relates to an apparatus and method for manufacturing dimensionally stable articles. The method includes providing a mold having an internal cavity that outlines the shape of the article, introducing metal or ceramic particles into the mold in an amount sufficient to provide the article in a desired size, vibrating the mold to compact the particles therein, adding a solution comprising an organic fluxing agent onto the compacted particles with the solution carrying the organic fluxing agent into interstices between the particles, freezing the solution to form a solid green article, heating the green article to vaporize the solution and fluxing agent and form a dry article, infiltrating the dry article with a molten metal having a lower temperature than that of the particles, and recovering the infiltrated article for finishing as a final article.
