There’s not really such a thing as superconductivity for a fine powder, so people are having trouble determining if this material even superconducts.
edit to clarify: Bulk here refers to having a single chunk of the material, and does not refer to the total quantity. Some physical properties only exist or only surface in chunks of material, not in the powder form.
- XorNot 3y agoConversely, the tape-type high temperature superconductors are generally made with a colloidal deposition process - which is based on a powder as a starter material. Assuming this is real, that would be the obvious process by which to try and build useful conductors and magnets - it also suggests a refinement process (passing it over a magnet would quantum lock superconducting grains and let the rest slide off).
