Blue Tungsten Oxide Forms Influence Tungsten Powder Particle
Blue tungsten oxide forms including composition, phase composition, surface area, particle size and oxygen index and so on. Blue tungsten oxide particle size has a significant impact at the tungsten powder reduction on tungsten powder particle size, which the coarse blue tungsten is good for producing fine tungsten powder, because coarse blue tungsten oxide particles in the process of reduction has good permeability can exclusion vapor water which have a greater advantage. To a certain extent, blue tungsten oxide specific surface area also affect tungsten powder particle size having a large specific surface area of blue tungsten oxide in favor of producing fine tungsten powder. Because the more advanced blue tungsten oxide surface area, the greater its reaction interface, reducing activity, the better. In the study also found the relative composition of blue tungsten oxide will effect tungsten powder particle size this is also can not be ignored. ...
