Discussion Overview

The discussion revolves around sourcing ceramic high-temperature superconductors, specifically for demonstration purposes. Participants are exploring options for acquiring these materials, including kits and individual components, and discussing their experiences and needs related to superconductors.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks a small ceramic superconductor, ideally a 1-inch diameter disk or ring, and asks for sources.
  • Another participant suggests searching for "YBCO demonstration kit" and provides links to potential suppliers, noting that YBCO can be made with the right equipment and expertise.
  • A different participant expresses interest in obtaining a superconductor to test a shield blueprint.
  • One participant mentions that while kits are readily available, they are looking for a source for just the superconducting ceramic discs due to the degradation of the material after use.

Areas of Agreement / Disagreement

Participants generally agree on the need for sourcing ceramic superconductors but have differing views on whether to purchase entire kits or individual components. The discussion remains unresolved regarding the best sources for the specific materials needed.

Contextual Notes

Some participants mention the degradation of superconducting materials after use, which may affect sourcing decisions. There is also a reliance on specific equipment and expertise for making YBCO, which may not be accessible to all interested parties.

Who May Find This Useful

Individuals interested in high-temperature superconductors, including students, educators, and hobbyists looking for demonstration materials or testing components.

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.

I would like this also so i can test my shield blueprint.
 
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.
