Naturally conductive material?

[gentlevoice]

Hi,

I'm looking to find a naturally conductive material e.g. a fluid from trees, plants or ?? something similar that has a very high specific resistivity maybe around 1/10th the resistivity of copper....

Anybody has suggestions?

Best regards,

Jesper

Carbon. Burn a tree and that's what you get.

I guess you want something with 1/10th the conductivity of copper - 10x the resistivity.

At room temperature, copper has a resistivity of 1.78x10^-8 Ohm m.

There are several naturally occuring metals with resistivity round 10^-7 to 2x10^-7.

For example, Iron is about 10^-7, Tin is 1.1x10^-7, Platinum close to tin (but much more expensive) and lead is about 2.2x10^-7.

copper, gold, platinum group metals all occur in "native" form - as the relatively pure metal

Thanks for the suggestions!

@ SY: Some time ago I bought a piece of carbon for drawing, however, it has very high resistance... Do you mean graphite?

I was wondering though if one of you knew of a naturally occuring material that I could pick up in the nature if I went for a walk (to aim high). It might be gold if I'm lucky

May I ask what the application is?

Hi Per-Anders,

Yes, it is for ultra-thin (highly) conductive membranes.
