Crystal structure, oxygen nonstoichiometry and diffusion mobility in some ferrites-nickelites
Crystal structure, thermal expansion, oxygen non-stoichiometry, electrical conductivity and diffusion characteristics of two analogous LaFe0.7Ni0.3O3−δ and PrFe0.7Ni0.3O3−δ compositions were investigated depending on temperature (20–1000 °C) and oxygen partial pressure (0.6–21000 Pa). The found oxygen diffusion and oxygen exchange coefficients for the both compositions at similar conditions are near to each other and varied in the range of 1·10−7–1·10−5 cm2·s−1 and 5·10−6–1·10−4 cm·s−1, respectively.
