Interaction of Yttrium–Barium Cuprate with Fluorine

The interaction of yttrium–barium cuprate with fluorine (0.–1 atm) has been studied at 20–-310 °C, the intensity (rate) of the interaction showing a deep minimum near 100 °C; our observations indicate that below 100 °C the interaction mechanism is dominated by fluorine intercalation in the vacant oxygen sites of yttrium–barium cuprates.
