TUNGSTEN ELECTRODE FOR ELECTROLYSIS OF SALT MELT FOR PRODUCTION OF RARE-EARTH METALS AND METHOD OF ITS PRODUCTION Russian patent published in 2024 - IPC C25C7/02 C25C3/34 C22B59/00 

FIELD: electrolysis of rare-earth metals.

SUBSTANCE: invention relates to tungsten electrode for electrolysis of salt melt for production of rare-earth metals and method of its production. Tungsten electrode comprises an open tungsten shell and a copper alloy housing. Note here that said housing is located inside open tungsten shell. Between the side wall of the copper alloy housing and the open tungsten shell, a tungsten buffer layer is provided, which has thickness of 3 to 8 mm and density of 12 to 14 g/cm³, note here that the bottom of the copper alloy housing touches the inner bottom of the exposed tungsten shell.

EFFECT: inventions make it possible to obtain a tungsten electrode with low weight, with good electrical conductivity, while reducing power consumption of the tungsten electrode.
