Carbon can produce volatile impurities, such as the CxHyBrz compounds (BP= 3.5° C to 190° C). Several metal bromide hydrates are also of relatively high volatility (for ex., FeBr3· H2O, Vapor Pressure @ 40° C is 11.9 Torr). ... In the presence of a halogenated gas such as WF6 the hydrate is no longer inert.
