  • Publication number: 20140196664
    Abstract: Condensable materials, such as but not limited to tungsten fluoride (WF6), can be used deposit films in a chemical vapor deposition (CVD) process. Described herein are methods to collect and reuse the condensable materials that are unreacted in the production process rather than treat these materials as waste. In one embodiment, when a condensable material, such as gaseous WF6, is not supplied to the CVD reactor, it is redirected to a recovery cabinet for capture.

  • Publication number: 20090297925
    Abstract: The disclosure relates to new compositions comprising an, B12FxH12-x? anion that may be prepared chemically or electrochemically by oxidation of B12FxH12-x2? salts. This anion can be generated electrochemically in a voltammetry experiment, or by chemically by treatment of the (2?) anions with powerful oxidants such as XeF2 or NO2(+) salts. The new compositions can be used as 1 electron chemical oxidants and in electrochemical cells such as lithium ion batteries where their fomation at elevated potential can serve to limit the upper limit of voltage during the overcharge of such a cell.
