Abstract:
The mass spectra of the high-temperature vapors over a series of barium tungstates have been measured. It is shown that the dominant vapor species over these mixed oxides is BaO(g); Ba(g) also is present as a minor vapor species over some of these oxides. The spectrum for Ba2CaWO6 shows Ca(g) in addition to BaO(g) and Ba(g). It appears that the BaO is formed by the solid state dissociation, e.g.
