Default Anything that I can do with my graphite?

Hello, everyone.

I have this stash of graphite powder from when I was younger and was into forensics and stuff. I mercilessly raked out the entrails of many pencils which met their imminent doom at the end of an unused staple. Today I carry the priceless memorabilia in a small mechanical pencil lead container, while it waits for it's chance to break free and return the long-suffered pain and agony in which it endured before my ruthless rampage for fingerprint powder!

Anyways, I was wondering if there was any electronic application for graphite where I could improve the quality of a component or tweak the performance of a circuit. I have no clue about the physical properties of graphite, so I am wondering if it could be used for inductors in some way. could it be rubbed on to an inductor core and have some type of effect? It makes things look shiny when rubbed on, so maybe that could be utilized. Or maybe it could be used in a speaker, maybe, between the coil and the magnet to reduce friction or soften the sound. I do know that this powder is very soft, so I'm thinking that it could be used as some sort of solid lubricant, maybe to help connectors slide together more easily, but graphite is resistive, so I don't think that that would work very well.

Any ideas?

I'm sure I read of graphite powder being used to coat mylar to make ESL panels. You might want to dig around in the ESL forum. Other than that, I can only think it would be useful for mechanical lubrication, but nowhere where its conductive properties would interfere with operation.

Hi

Isn't the stuff conductive? I think you should use some caution as to where you apply it. How about setting up a neighbourhood locksmithing biz, servicing seized locks?

Most pencil lead consists of a mixture of clay and graphite. The softer the lead, the more graphite there is in the mix.

Yes, you can use graphite to coat diaphragms for ESLs, but it tends to make a low resistance coating which is not well suited for drivers that are to reproduce low frequencies. These days a spray called Licron is easier to apply and provides better results.

Graphite is available as a lock lubricant at any hardware store or WalMart. For about $2 you can get pure graphite in a much finer powder than you can ever hope to produce from pencils...

I don't think I'll start a locksmithing thing, because too many people can just o to walmart and buy their own lubricant stuff. I don't like those packages that you get for the graphite at walmart, though. One small slip and POOF! Your covered with graphite and there's nothing left in the bottle! I'll have to remember that, though, 'cause if I ever want any fingerprint powder, I know where to go! I'm sure I'll find a use for it. I would think that it's too soft to go in my Xmod's (build-your-own remote racecar from radioshack) bearings, it would just let the bearings grind themselves to bits. Maybe I'll make a van de graph generator and see if I can make them float! Wouldn't that be cool...

Any word on the magnetic properties of graphite?
