Description

Existence of gaseous niobates of alkaline-earth metals was ascertained by the method of high-temperature mass-spectrometry. Equilibrium constants involving the molecules and the relevant oxides were calculated, the standard enthalpies of formation and atomization for gaseous BeNbO3, CaNbO3, SrNbO3, BaNbO2, BaNbO3 and BaNb2O6 were determined

Abstract (Russian)

Методом высокотемпературной масс-спектрометрии установлено существование газообразных ниобатов щелочноземельных металлов. Рассчитаны константы равновесия с участием этих молекул и соответствующих оксидов, определены стандартные энтальпии образования и атомизации для газообразных BeNbO3, CaNbO3, SrNbO3, BaNbO2, BaNbO3 и BaNb2O6
