Product Detail
99.95% Pure Tungsten Powder with Size ranging from 0.4 to 20 microns
Description:<
99.95% Pure Tungsten Powder with Size ranging from 0.4 to 20 microns
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.
Tungsten particle size increases with the rising temperature. And the size range we can produce 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.
