Method and System for Producing High Compact Strength Tungsten Powder

Disclosed is a method for producing high compact strength tungsten powder.

Ammonium paratungstate and purple tungsten oxide serving as raw materials are uniformly mixed according to a certain proportion, mixed powder is placed into a hydrogen reduction furnace, the thickness of a material bed is 5-25mm, the mixed powder is heated up to 700-1100 DEG C at the speed of 5-20 DEG C/min and is directly reduced with hydrogen, holding time is 1-5 hours, the dew-point temperature of the hydrogen ranges from -40 DEG C to -65 DEG C, and finally, reduced powder is sieved to obtain the high compact strength tungsten powder. The tungsten powder produced by the method can be pressed into high-strength compact without adding any forming agents, the compact strength of the tungsten powder is as high as 3.0-5.0MPa, and a tungsten product made of the tungsten powder has the advantages of high density, fine high-temperature resistance, stable quality and the like.

The preparation method and preparation steps are quite simple, and technological parameters of the preparation process are easily controlled.
