Abstract

Water, an ubiquitous impurity in all phases of materials processing, degrades the near-infrared transmission of metal halides and oxides. With the halides, one deals with both the oxygen and hydrogen impurities derived from H₂O, while with the oxides, only the H-impurity. The electrolytic and thermal dissociation modes of H₂O become significant at the much higher process temperature of the refractory metal oxides. Because of the high strength of the oxide ion as a Lewis base, halogen atoms are unable to abstract the proton of the H-impurity. However, they can displace by electron transfer the H-impurity as the unit OH, a pseudohalide. The limitation and application of the use of halogens to clean up H-impurities in metal oxides are demonstrated with the use of basic and acidic metal oxides.
