摘要
Evaporation of perovskitewas studied by high-temperatureKnudsen effusion mass spectrometric method at 1700-2200 K. Vapor species typical for simple oxides and a small amount of CaTiO3 complex gaseous oxide were identified in the gas phase over perovskite. For the first time, the partial pressure of vapor species in the gas phase over perovskite are compared with those corresponding to simple oxides, showing the predominant effect of the calcium component of perovskite on evaporation character.
