What is the conductivity of hematite (Fe2O3)?

01 August 2023 0 4K Report

Hi, I would like to know the conductivity of hematite - it is suprisingly hard to find. I would be happy over any answer with reference.

Thanks

Why does corrosion starts at grain boundaries although the energy level of the surface free energy is higher than the energy of grain boundaries?

It is argued that corrosion starts at grain boundaries or other imperfections because of (amongst other things) the higher energy level compared to the bulk material. Also in grain boundary...
