Si. Lopatin et al., Thermochemical study of salts of oxygen-containing acids in the gas phase:VI. Barium metaborates, RUSS J G CH, 71(1), 2001, pp. 61-66
Vapor formation in the BaO-B2O3 system was studied by high-temperature mass
spectrometry. The equilibrium reactions with participation of gaseous bari
um metaborates were determined. The standard enthalpies of formation of gas
eous BaB2O4(g) and BaBO2(g) of -1424 +/- 28 and 598 +/- 15 kJ mol(-1), resp
ectively, were evaluated.
