Ferrite self-diffusion

Haneda H, Yamamtrra H, Watanabe A, Shirasaki S (1987) Relatiortship between oxygen self-diffusion and Debye temperatrrre in the polycrystalline magnesitrm altrmintrm ferrite series, MgAl2 xFCx04. J Solid State Chem 68 273-284... 

Self-diffusion of 0 ions in polycrystalline and single-crystal magnesioferrites was measured by using a gas-solid isotopic exchange technique, with as a tracer, at 975 to 1465C. The bulk diffusion coefficients of polycrystalline magnesio-ferrite (MgO/Fe203 mole ratio = 0.95) could be expressed by ...
