Factor Influencing Rare Earth Tungsten Electrode - Uniformity of Rare Earth Doping

Rare earth tungsten electrode is electrode doped with rare earth, including doping one element, two elements and three elements or more. Manufacturing process and the raw material will influence electrode quality.

Solid-liquid sintering is a good choice for uniform doping to produce tungsten electrode. Raw materials are APT (ammonium paratungstate) and rare earth nitrate. The doping process is to make nitrate mixing with APT together, which is benefit for the later decomposition of rare earth and doped into tungsten crystal to reach a result of uniform doping.
