Cation tracer diffusion coefficients, DMe*, for Me=Fe, Mn, Co and Ti, were measured using radioactive isotopes in the spinel solid solution (TixFe1-x)3-δO4 as a function of the oxygen activity. Experiments were performed ...
The deviation from stoichiometry, δ, in spinel solid solutions of the type (TixFe1-x)3-δ O4 with x=0.1, 0.2 and 0.25 was studied thermogravimetrically as a function of oxygen activity, aO2, at 1100, 1200 and 1300 °C. The ...
