Carbonyl Iron Powder

[Frank Gentges]

Tacoistas,

I have had the good fortune to come into the possession of several 
pounds of carbonyl iron powder.

This powder is a very very finely divided iron powder and usually the 
particles are coated with some compound of iron to act as an insulator 
that reduces eddy currents.

In the past I have put this powder into a PVC pipe to make something 
similar to a ferrite or powdered iron rod.  These make a nice portable 
LF receiving antenna.  I don't think they would do much above a couple 
of MHz.

I anyone is interested in trying some of this powder get in touch with 
me and I will make some available.
