摘要：

Small amounts of oxide impurities in alkali chloroaluminate and fluorochloroaluminate melts can complicate markedly the electrochemical and spectroscopic behavior of other solute species in these melts. A simple method for the removal of oxides from these melts has been developed in our laboratory. This method is based on the reaction of carbon tetrachloride with oxides to convert them to chlorides. Spectroscopic techniques (UV-visible and IR spectroscopy) have shown that addition of carbon tetrachloride results in the complete conversion of oxides to chlorides.
