AD 3.30 g / cm3 Tungsten Powder with High purity W 99.95%, 3.28 μm Grain Size

Description:

Our tungsten powder is fabricated through reduction reaction of ammonium paratungstate with hydrogen under a heating up circumstance. The purity of product depends on reduction process which can be affected by temperature, loading quantity, moving rate of containers, gas speed and etc. And the size range we can produce is between 0.4 and 20 microns.

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 those 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.
