Are you asking about the micro probe, or the metal oxides.  I think that the heat of the arc is sufficient to oxidize the metals in the dust.  Many metal oxides are insulators.  I just am not sure of the three I mentioned.  As more residue builds up on the track and wheels, the more arcing we get.  My LGB mallets do not have any sliders for additional power pickup.  I have to clean their wheels much more frequently than any other engines.  

We use the micro probe in the laboratory to analyze very small geologic material, down to dust size, tens of microns in size.

After I posted this, I reviewed a long thread on the subject of the origin of black dust on My Large Scale.  I did not wipe the rail after two loops.  I ran some engines, Mallets, for 2.5 hours.

Here is a link to the thread.
