ABSTRACT:
A process creates molded pans by reaction injection molding (RIM) of inorganics. Two or more slips are mixed as they are being fed into a mold and the slips react rapidly with each other to form a mechanically strong part. The slips contain ceramics/metals which chemically react to form a binding phase, or which destabilize, floe, or gel to form the part. The formed part is then removed from the mold and used as is, or heat-treated prior to use. With this forming process, setting times are independent of part size, unlike slip casting or injection molding, and there is no requirement to add or remove heat from the mold to form the part.
