Ga. Semenov et Si. Lopatin, Thermochemical study of gaseous salts of oxygen-containing acids: VII. Alkaline-earth metal niobates, RUSS J G CH, 71(6), 2001, pp. 828-832
The existence of gaseous alkaline-earth metal niobates was established by h
igh-temperature mass spectrometry. The constants of equilibria involving th
e niobates and the corresponding oxides were calculated,and the standard en
thalpies of formation and atomization of gaseous BeNbO3, CaNbO3, SrNbO3, Ba
NbO2, BaNbO3 and BaNb2O6 were determined.
