Dark grey Tungsten Powder above 99.95% W content, Oxygen Content < 0.25%

Description:

Our tungsten powder is fabricated through reduction reaction of ammonium paratungstate with hydrogen under a heating up circumstance. We can offer particle size of tungsten powder is between 0.4 and 20 microns.

The standard to judge tungsten powder quality on one hand lies in chemical composition control. On the other hand which is also significant, oxygen content must be limited within its relative range according to different F.S.S.S. Taking all above parameter in control not only ensure the quality of tungsten powder, but its derivative products.

The relevant physical properties of tungsten powder are average particle size, particle size distribution, apparent, tap, and compact or green density, specific surface other and can be influenced by the oxide properties and reduction conditions. They represent the important criteria for further processing and are responsible for the compactability, sintering behavior, dissolution reactions during liquid phase sintering, and carburization reaction.
