Rare earth doped tungsten powder is a kind of tungsten powder doped with rare earth elements. It has a finer grain size, higher purity, and a regular cubic shape of powder, with higher potassium content. The doped tungsten products prepared with rare earth doped tungsten powder have excellent properties at high temperature and normal temperature.
Under the condition of the same reduction process, rare earth elements can reduce the reduction rate of doped tungsten powder, split time later. In the end superfine tungsten powder can be obtained for several hundred nanometers, and its size is smaller.
After reduction, the shape of the powder is transformed from a quasi-spherical shape to a regular cubic shape. The rare earth elements promote the increase of potassium content in tungsten powder, and the addition of rare earth elements can make the reduction of tungsten oxide more thorough and obtain higher purity of tungsten powder.
