Abstract:
This work reports on the investigation of thermal behavior of Fe(II,III)-containing borates by in
situ low- and high-temperature X-ray diffraction methods, Mössbauer spectroscopy and thermal analysis.
A combination of the methods in the revealing of magnetic phase transitions, investigation of the Fe2+ to
Fe3+ oxidation occur with an increase in temperature using data of these methods showed a good
compatibility between each other. Thermal expansion of the borates is described from a viewpoint of
crystal chemistry of compounds containing cation- and oxocentred polyhedra.
