Tungsten bromides

Titanium bromide [7789-68-6] TiBr, is claimed as a catalyst for olefin polymerizations (18). Chromous bromide [10049-25-9] CrBr2, is used in chromizing. Chromic bromide [10031-25-1], CrBr, and tungsten bromide [13701 -86-5], are catalysts for polymerizing olefins (19). Manganese...

A stoichiometric mixture of 2.758 g. (15 mg. atoms) of tungsten powder, 6.956 g. (30 mmoles) of tungsten(VI) oxide, and 7.192 g. (45 mmoles) of bromine is put into the reaction tube. A small excess of 2 mg. of bromine per milliliter of tube volume is added to prevent the formation of lower tungsten bromides or bromide oxides. 

Oppermann (1 ) made careful pressure measurements on the systems MoBrg(cr) + Br2(g), MoBrg (cr) -r MoBrg(cr) + Mo(cr). Brewer ( ), by comparison with the tungsten-bromide system, indicated the possibility of intermediate phases between MoBrg and MoBr and thus modified the treatment of the data. Brewer used a 3rd law treatment combined with... 

The latest type of incandescent lamp is the cluster lamp. A tungsten bromide vapor in a bulb is excited by a plasma with external electrodes. Light is emitted by 2-nm tungsten particles that form in the center of a plasma, where they reach a temperature of 3300°C. At a lower temperature near the bulb wall the particles react with bromine and form the gas that decomposes again at the higher temperatures in the plasma.
