Abstract
Gravitational sag and shape distortion by friction over supporting hardware during binder removal and sintering of green bodies made from sinterable particulate materials are overcome by processing in a supercritical fluid medium at a pressure whereby the density of the medium approaches or equals that of the green bodies.
