Description

  • Content Description: New results on the point defect chemistry of (Ni{sub x}Fe{sub 1-x}){sub 3-delta}O{sub 4} and on the cation tracer diffusion in this spinel solid solution are presented and discussed. The equation system for the defect chemistry of perovskites of the type A{sub 1-x}B{sub 1+x}O{sub 3-delta} have been worked out and used to derive Kr{umlt o}ger-Vink diagrams. The deviation from stoichiometry, delta, in LA{sub 1-x}Mn{sub 1+x}O{sub 3-delta} has been measured at 1100, 1200, and 1300 degrees Celsius as a function of the oxygen activity and the composition variable x. At high and low oxygen activities, the data were fit by taking into account the electrostatic interaction between the charge defects by making use of the Debye H{umlt u}ckel theory.
