Abstract
The chemistry of tungsten chlorides in the LiCl/KCl eutectic has been investigated by Raman spectroscopy between 400 and 500°. It has been found that W(VI) is reduced to W(V) directly by the free Cl− ion in the melt and the octahedral complex ion WCL−6 is formed. Addition of metals (Al, Zn, Pb, W) causes further reduction of W(V). Depending on the metal added WCl2-6 or W metal can be obtained.
