I am not sure if this should be here or not, but I managed to make some diamagnetic graphite (naturally occurs as "vein" graphite) that is only available in little pellets and crumbs about .5 to 1.5mm in size so it makes it kinda useless really as crumbs, and I had seen someone had used a grinder to grind it up into powder then press it together to get a sheet, but instead of grinding I just used high pressure and a containment of a sheet of paper folded up to hold it all together.

when done you get a sheet that is kinda delicate. so I sprayed it with clear spray paint and it was much more stable when done :)

pics of the sheets after done

video of the granules to show size a bit :)

working on something new that I have detailed more in the general discussions that is a paint-able diamagnetic coating for shielding (my purpose for making it but there may be many other applications like sleeves to go around tesla coils that slide up and down to tune them in other manners, and the like)

the material in this new attempt is bismuth turned into a super fine (think baby powder) particle while still in a metal state (not combined with other elements to make salts) and while it is only a quarter of what graphene or highly ordered graphite which is what the original post here is displaying, it is not meant for levitation or anything like blocking magnetic fields all on its own (even graphene can not do that effectively as diamagnetic fields are not really very strong on any material) I am shooting for making super saturation highways for magnetic energy to be redirected into using a layer of steel between two layers of bismuth by tinning the surfaces of the steel using flux and bismuth powder,

I have had good success too considering my method of heating (soldering iron tip on a sheet that was a triangle of steel about 1 inch on either side of the right angle :) ) so I have confidence that larger pieces with a thin coating heated with a heat gun pushing out only 40 to 50 more degrees higher than the melting point of the bismuth should be sufficient to completely tin my surfaces evenly for later lamination :) any comments, ideas, questions feel free to ask or state here or over on the main thread close to the top of the general forum as of the posting of this comment :)

I like Bismuth mainly because it's non-toxic and easy to work with.
Yet I'm finding it weak as a diamagnetic.

Well that is for my purpose..
I need to go much further than a coating.
Hence my casting of almost 1/4"..

I've been searching for a good chart of minerals/components that list diamagnetic strengths..
You have one, please share..

Funny how easy it is to find one that shows magnetic strengths..

Hi ODR

I have been trying to keep up but OLD DOG RULES can't teach thing LOL (ME)
I did find this trying to understand what you are doing. Chart at the bottom.

I've also found this

There are others out there like, Pyrolytic carbon
Which has 3 times diamagnetic quality.

Thank God they put them in order.. also LOL

I haven't found one 'yet' of 'man-made' products.
That's where Pyrolytic carbon would fit in..
Or maybe that's all they telling us about for now..

the issue I found with carbon based compounds is that the whole unit is not diamagnetic, like graphene sheets it is diamagnetic from one axis but on the other axes it is very strongly paramagnetic, ie the flow through it causes a diamagnetic response more than the individual atoms causing this effect unlike bismuth, where even a single atom is diamagnetic. I have other ideas on the subject but I am sticking to voice over skype or oovoo or some other voice chat to discuss this, as it can and does get very lengthy when talking about it, however I have OBS to record audio and video off my screen and speakers so anyone wanting to listen in later I dont mind sharing with, I just dont want to fall into one of those traps of :"hello my name is such and such and this is MY discovery/invention" on youtube. :)

oh I should note that I will not post anything from OBS or share it that I record of our conversation should we decide to do so, as a group unless everyone in the conversation is ok with sharing it as well. :)
