摘要: A method for recycling thoriated tungsten objects such as thoriated tungsten scrap resulting from the fabrication of electrodes for lamps. The thoriated tungsten objects are oxidized, homogenized by mixing and chemically reduced under a hydrogen gas atmosphere to form thoriated tungsten. This method eliminates the need to separate the tungsten from its dopants. The thoriated tungsten obtained as the end product is returned to the production process and is preferably used as a raw material for the production of welding electrodes or thoriated tungsten discharge lamp electrodes.
