Searching for online YBCO Superconductor supplier

[JoeOh]

I would like to do some experimenting with some superconducting YBCO toroid disks measuring about 2" in outer diameter, 1" inner diameter, and 1/2" thick. I've tried to search for a price list on the web with no luck. I even tried Ebay.

 

I hope they are not terribly expensive as I need 4 of them. It would be great if the sizes were close to what I have stated.

 

Thanx-

you'll also need liquid nitrogen to keep them cool and in the superconductive state.

Of course I know that I gotta use LN2. At least LN2 is on the cheap side. If anything, I'll be more worried about safety issues.
