ABSTRACT:
A tetrafluoroethylene-type fluoroplastic powder is added and mixed with a metal powder and the mixture is shaped. The compact is heated in a nonoxidizing atmosphere and the oxides on the surface of the metal particles are converted and removed as gaseous fluorides. Alternatively, after the oxides are converted to solid or liquid fluorides, the fluorides are reduced by hydrogen and then they are removed as gaseous reaction products. Thereafter, the compact is sintered.
