Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength.
Submicron tungsten powder Compared with ordinary tungsten powder, the particle size of submicron tungsten powder is smaller, about 200nm, and has higher chemical activity and a larger specific surface area. The oxygen content of the powder can be controlled below 1% after passivation. Preparation Method of Tungsten Powder The preparation method of tungsten powder includes […]
