Sintering composites made of plasticized W-Mo powders and hafnium oxide

The compactibility in uniaxial compacting of plasticated granules of tungsten-molybdenum mixtures and also of multilayer composites of films of the powders of hafnium and tungsten oxides and their cermets, cast using a rubber binder, is considerably higher than that of the “dry” tungsten powders. The density of the compacted composite specimens increases and linear shrinkage decreases with the increase of pressure to the critical value (500–600 MPa) and then remains unchanged but the final density after sintering at 2000°C does not depend on the compacting pressure.
