YBCO Super conductors:
We are attempting to make YBCO (yttrium-barium-copper-oxide - YBa2Cu3O7) Superconductors in the Science Committee at DMS.
Comprised of the following chemicals in a 1-2-3 ratio:
- Yttrium Oxide
- Copper (Cupric) Oxide
- Barium Carbonate (TOXIC)
Equipment:
- Furnace capable of 1000 Degrees Celsius
- Alumina Crucible
- Oxygen source
Demonstration:
- Liquid Nitrogen
- Rare-earth magnets
There are two primary methods for making YBCO: the "Shake and Bake" method and the Pyrolysis method. We are first attempting the Shake and Bake method.
