Electrical Resistivity of Rust vs. other materials

Electrical Resistivity of Rust vs. other materials

Electrical Resistivity of Rust vs. other materials

(OP)
I'm looking for information on electrical properties of iron oxide (FeO3) relative to other materials (metal and nonmetals), such as silica, nickel, steel,  etc... Does anyone know where I may find such information?

RE: Electrical Resistivity of Rust vs. other materials

Some of us old timers would turn and take our CRC Handbook of Chemistry and Physics, and just look it up.
There is an online handbook from NIST on physical properties.  For non-metals the product forms will be critical.  Rust on a surface will have much different properties from a full density iron oxide ceramic.

Shame on me, but CRC is not in my library.  I'm interested not so much in the full density iron oxide, but more in the incidental surface iron oxide.  Thanks for the post.

You might want to try Scirus and if you have access I would try Metadex. I would think there has been a lot work with FeO3 in the coatings industry. Whether any is published is a big ?.  

Our electrochemical group did a lot of work on the conductivity/resistivity of iron oxides but was mainly with various forms of Fe3O4 for use as electrodes in electrochemical processes. I don't recall any work with plain rust other than we wanted to start with  zero-valent iron when we used iron as the anode in electrochemical cells cells.

RE: Electrical Resistivity of Rust vs. other materials

I'm not sure where I would go to to look up the info, other than the obvious, but I want to point out that rust is not simply iron oxide,  so end up wondering what material or substance are you really interested in?

RE: Electrical Resistivity of Rust vs. other materials

There will be variables in both density and moisture content that will change resistivity a lot.
I would bet that you can find data on weathering steels (Corten) that have to do with measurements of surface rust.
