Electrical conductivity measurements of bridgmanite with various Al contents and a constant Mg# of 90 were performed at temperatures ranging from room temperature up to 2000 K at pressures of 26–28 GPa in a Kawai-type multianvil apparatus by impedance spectroscopy analysis. The incorporation of Al into bridgmanite raises its electrical conductivity significantly, but it is a small conductivity variation with respect to the quantity of Al. Synchrotron Mössbauer spectroscopy of recovered samples showed significant amounts of ferric iron in aluminous bridgmanite. The mobility of the charge carriers in bridgmanite was calculated based on the conductivity and the Fe³⁺/ΣFe ratio. The relationship between the logarithm of the electrical conductivity and the reciprocal temperature is consistent with Fe²⁺–Fe³⁺ electron hopping (small polarons) as the dominant conduction mechanism at low temperatures (<1400 K) and …
