Electrolytes for Tungsten Refining

Electrodeposition of Tungsten from Molten KF–KCl–WO3 and CsF–CsCl–WO3

“…Thus, the electrodeposition of flat and dense tungsten coatings is worth investigating. Numerous studies have reported the electrodeposition of tungsten from the high-temperature molten salts, such as fluorides, 1,2 chlorides, [2][3][4] fluoride-chloride mixtures [2][3][4][5][6][7][8] and oxides. 2,3,9 It is known that dense and coherent tungsten deposits are more easily obtained from molten fluorides than from molten chlorides.…”
