Electrical Conductivity of Al3+-doped MgO (original) (raw)

Abstract

Periclase is thought to comprise about 15-20% of the lower mantle, making it the second most abundant phase present after magnesium silicate perovskite. Because cation diffusivity in periclase is relatively rapid compared to magnesium silicate perovskite, it may control bulk transport processes in the lower mantle. It is expected that trivalent cations such as Fe3+ and Al3+ are dissolved in
