Ternary rare earth tungsten electrodes containing La2O3, Y2O3, CeO2 to any of the three rare earth oxides in two, each rare earth oxide content is 0.45% ~ 1.75% total rare earth oxide content of 2% ~ 2.2 %. After reduction, model, pre-sintering, melting down sintering, swaging, drawing, polishing and processing into a variety of electrode processes. The electrode arc performance, service life than thorium and cerium tungsten electrode tungsten, used as inert gas welding and plasma welding, cutting, painting, melting, and special electrical light sources.
