Electrical Conductivity of Pure and Fe-Doped Magnesium-Aluminum Spinel

The electrical conductivity of nominally pure and Fe‐doped MgAl2O4 spinel was measured at 700 to 2000 K. The results for pure stoichiometric spinel can be fitted by exponential expressions with different activation‐energy parameters in three ranges of temperature. The conductivity of a sample contai...
