Something interesting I found, about diamagnetic material. Might prove usefull to someone...

Subject: Bismuth/Pyrolytic Carbon foil Laminates, Diamagnetics. onthecutting...
Hello.
I'm a researcher who would like to inquire about very thin foil sheets of Bismuth.
The Bismuth sheets must be less than 1/128th of an inch.
The second Material to Inquire is less than 1/128th of an inch of Pyrolytic Carbon foil sheets.
If these two materials are in stock I would like to receive information of volume and pricing.
These materials are for special research in Bismuth/Pyrolytic Carbon laminates for the use in Highly Diamagetic field studies. These two materials when Laminated in multi layers achieve above normally high Diamagnetic material at room temperature normally only seen in Superconductors. Although the Superconductivity is not presently seen in this material the Diamagnetic fields are exceptional when all the Pyrolytic Carbon sheets are oriented unidirectional as a laminate with the Bismuth sheets.
Research.

Just imagine what's waiting in the wings for graphene and dendritic bismuth...

Wonder whatever happened to that website...."surfing the apocalypse"?

Gerald,
you will find pyrolytic graphite sheets (PGS) of desired thickness at the Panasonic Electronic Components,

Thank you, not sure if I personaly want them, but thanks. I'm sure someone does.

ace569er,
I obviously failed to distinguish your own message from the quote you added,
but as you politely indicate, there may be someone interested in the information anyway.
An interesting fact is that Bismuth becomes a semiconductor when deposited in sufficiently thin layers on a substrate,
and will reach anomalously high resistivity peaks at certain electromagnetic frequencies, unlike any other known metal.

That is interesting. I'm trying to figure out how Magnetic shielding; TS5 & TS9 are made. Bismuth has a resistance to magnets, that is the same as air. Meaning that if a magnet is placed next to Bismuth then nu-metal. The space needed to not attract to the metal, is the same distance as if there was no bismuth, and just an air gap between the two. Were as pyrolytic graphite may hold a different property, along one axis. Even though all 6, axises, are needed. When combined they may help, to solve that, but doubtful. The TS5-9 look like a ceramic or composite base. Which I would assume would destroy pyrolytic graphite's properties, if made in to a composite. No idea though, sadly. Also how many other elements can be vapor/heat alined like carbon(pyrolytic graphite)? To give them diamagnetic properties, like that, which has been achieved in pyrolytic graphite? :P
