Description

Mechanism of Nb2O5 interaction with MHF2 (M = K+, NH4+) was investigated by the methods of thermogravimetry, mass-spectrometry, X-ray diffraction and IR-spectroscopy. In both cases fluorination proceeds in one stage with formation of M3NbOF6. The observed complex form of polytherms of properties, H2O pressure for example, is explained by passivation of Nb2O5 particle
