How do we compare the loop inductance and skin depth at low and high frequencies of these two materials. Sort by date Sort by votes Tuesday at 8:15 AM #2 E Easy peasy Ferrites are usually ferrimagnetic ceramic compounds derived from iron oxides. Magnetite (Fe3O4) is a famous example. Like most of the other ceramics, ferrites are hard, brittle, and poor conductors of electricity. Many ferrites adopt the spinel structure with the formula AB2O4, where A and B represent various metal cations, usually including iron (Fe). Spinel ferrites usu…

WebDuring corrosion of such steel, the ferrite phase dissolves and a porous iron carbide network is exposed (see Fig. 7.6). Given that iron carbide is an electronic conductor, this porous network serves as an additional cathodic surface for reduction of corrosive species, which would lead to an increase in the corrosion rate.
