INJECTION MOLDABLE CERAMIC AND METALLIC COMPOSITIONS AND METHOD OF PREPARING THE SAME

Abstract

Provided is an injection moldable composition suitable for forming ceramic or metallic greenbodies. The composition comprises in combination an inorganic or metallic filler in an amount of from about 63 volume percent to about 92 volume percent, a binding organic matrix resin, and an organosilane processing reagent represented by the general formula: SiX.sub.1 X.sub.2 X.sub.3 X.sub.4 wherein at least one of X1, X2, X3 or X4 is an unfunctionalized alkyl or alkenyl group having 10 to 35 carbon atoms and at least one of X1, X2, X3 or X4 is an alkoxy group or halide, such that the moldable composition exhibits a low initial mixing torque upon mechanical agitation. These compositions offer excellent advantage in processibility using conventional mixing and molding equipment. Also provided is a process for preparing the moldable compositions.
