| titleOfInvention | Rare earth tungsten alloy electrode material and preparation method thereof |
| abstract | The invention discloses a rare earth tungsten alloy electrode material, which is prepared from the following raw materials: W and rare earth oxides; the weight percentages of the W and rare earth oxides are respectively 93%-95% and 3.5%-6.8%; The rare earth oxide is one or more of La2O3, Y2O3 and ZrO2; the average particle size of the La2O3, Y2O3 and ZrO2 is 2-3um; the content of the Y2O3 is less than the content of ZrO2; it also includes nanotube CNTs, The weight percentage of the CNTs is 0.2%-1.5%. The present invention also provides a method for preparing a rare earth tungsten alloy electrode material, including a method for preparing a precursor powder when preparing the rare earth tungsten alloy electrode material. When the precursor powder is calcined, the precursor powder containing tungsten, lanthanum, yttrium and zirconium is calcined at 560° C. and 4 h. The temperature, pressure and holding time for sintering raw materials are: 2000‑2300℃, 500‑750Mpa and 100‑150min. The invention effectively and comprehensively improves the material properties of the tungsten electrode such as electron generating energy, ablation resistance and strength. |
