AQUEOUS PROCESS FOR INJECTION MOLDING CERAMIC POWDERS AT HIGH SOLIDS LOADINGS

摘要

process for forming components from ceramic powder.in the process (1) to form a concentrated mixture containing more than 40% solids by volume, the mixture consisting of the ceramic powder.a material forming a gel selected from the class of polysaccharides known as "agarou00efdes and a solvent for the material to form a gel; this step is u00e9ffectuant shear in a mixer, and is heated to raise the temperature of the mixture until the approximately 70 to 100 degrees c; and (2) the mold the mixture to a temperature sufficient to produce a structure homogu00e8n(e) comprising the powder and the gel. the elements have excellent resistance to green and cook quickly without crack, deform or contract.
