摘要

用拉曼光谱在400 ~ 500°范围内研究了氯化钨/氯化钾共晶中氯化钨的化学性质。发现熔体中游离的Cl−离子直接将W(VI)还原为W(V)，形成八面体络合物离子WCL−6。金属(Al, Zn, Pb, W)的加入使W(V)进一步降低。根据加入金属的不同，可以得到WCl2-6或W金属。

Raman spectral study of WCl6 in alkali chloride melts

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 WCl^2-₆ or W metal can be obtained.
