Typical application of crystalline tungsten powder
manufacturing process:
Tungsten powder is made of tungsten oxide and recovered in a four tube muffle furnace or a multi tube furnace, with the particle size ranging from 0.6-30 microns. Mainly divided into coarse, medium and fine particle sizes, silver gray powder, and impurity content is based on national standards. Use of tungsten powder: mainly used for tungsten materials and tungsten metallurgical materials.
