Zirconium Tungsten Electrodes Object of The Invention of New Materials and Basic Design

Zirconium tungsten electrodes new material object of the invention is to provide a zirconium tungsten electrode new materials, in addition to ensure the use of performance indicators have reached the international zirconium tungsten electrode material , but also improve the zirconium tungsten electrodes new material ductility and stress processing performance, increase yield and expand its use .

Tungsten electrodes new material zirconium basic design of the invention to change the electrode material zirconium tungsten , tungsten oxide, zirconium content ratio , while the component is added to improve processing performance pressure , improve the ductility of yttrium oxide , cobalt ingredients, the object of the present invention .

Specific embodiments of the present invention is described below. Zirconium tungsten electrodes new material made ​​of tungsten , zirconia, yttria , four major components, which are cobalt , contains a very small amount of aluminum , iron, silicon , nickel, magnesium, copper , molybdenum and carbon impurities. The four main elements of the new tungsten electrode material content of zirconium contained in the ratios were : tungsten content 98 ~ 98.8% , content of zirconium oxide, 0.91 to 1.2% yttria content of 0.01 to 0.07% cobalt 0.01 to 0.02%. According to the above formula, according to conventional processes existing zirconium tungsten electrodes made ​​of new materials to replace thorium tungsten, cerium and zirconium tungsten electrode material , superior processing performance of the pressure existing foreign zirconium tungsten electrode material .
