“…The chlorination technique employs hydrogen chloride gas or hydrogen chloride-oxygen mixtures (24,76,78,92,126,127)• Hydrogen chloride-chlorine mixtures, chlorine, and nitrosyl chloride have been used at this laboratory for the same purpose (106). Bronzes will react with these gases to yield a mixture of tungstenyl chloride, WOgClg, oxygen or water, and alkali metal chloride.…”
