Ammonium Paratungstate Morphology and Distribution Effect on Tungsten Powder Particle Shape

The strength of tungsten powder compacts mainly results from particles of irregular surface for particle shape is one of the most important factors affecting strength of tungsten powder compacts. Ammonium paratungstate has great influence on the tungsten powder particle shape. The compact strength varies greatly under the same process and raw materials with different properties while producing high compact performance tungsten powder using ammonium paratungstate one step reduction. The features of ammonium paratungstate for producing high compact performance tungsten powder are summarized by the experiments.
