• Keywords: plasma reduction; hydrogen plasma; ammonium paratungstate powder; sintering;tungsten; tungsten carbide
• Description: New plasma chemical reduction techniques of tungsten precursors were investigated in order to produce tungsten powder with high sintering activity permitting to increase the density of tungsten compact products above hitherto technological limit. The application of non/isothermic hydrogen plasma allows the initiation of reduction processes at low temperature of neutral gas.
