Abstract

Precise control of the shrinkage upon sintering of bodies made from mixtures of particulate materials and organic binders is achieved through precision pycnometry of the particulate materials and of the resulting sintered bodies, thus allowing a single molding tool to be used to produce parts in different sizes and from different materials and to tight manufacturing tolerances.
