Where can I get a cheap ceramic (hi temp.) superconductor?

    I used to have one for demonstration....need to find a current source ...maybe a small 1 inch diameter disk...or preferably a ring. Any sources? Thx.

    Have you tried googling "YBCO demonstration kit"? Here are a couple of the first hits: http://www.superconductors.org/play.htm and http://www.can-superconductors.com/demonstration-kits.html

    If you have access to the correct equipment and a little expertise (it's an exercise for senior undergraduates) YBCO is also fairly easy to make. However, if you only need one bit, those kits above sound good.

    The kits are easy enough to find from any scientific supply house, like Arbor Scientific or the like. But I think the OP doesn't want to pay for the entire kit. I'm in the same boat. I have several kits, but the ceramic superconducting material degrades after a few uses and needs to be replaced. Drying it off after each use extends the life. If anyone knows of a source for just the superconducting ceramic discs please post. Thanks.
