Abstract: The paper has introduced a developed process for new type of electrode materials by adding rare-earth oxides including W-La, W-Y, W-Ce and W-Zr and given out its main technological parameters and the results of electric properties measured. It has been concluded by analyzing structures and properties that Y₂O₃ has the most obvious roles in fining alloyed powder and grain size of sintered alloys. The properties by adding W₄O₁₁ in matrix are superior than that by adding WO₃ in matrix. Furthermore, it has been known by the comparison of electrode materials that WLa₁₅ has best properties among several electrode materials studied.
