  • Process for the production of high temperature superconductor wires
    Patent number: 10840429
    Abstract: The present invention is in the field of processes for the production of high temperature super-conductor wires. In particular, the present invention relates to a process for the production of high temperature superconductor wires comprising heating a film comprising yttrium or a rare earth metal, an alkaline earth metal, and a transition metal to a temperature of at least 700° C. and cooling the film to a temperature below 300° C., wherein the heating and cooling is per-formed at least twice.
    Type: Grant
    Filed: March 16, 2016
    Date of Patent: November 17, 2020
    Assignee: BASF SE
    Inventors: Ron Feenstra, Mario Sadewasser, Michael Baecker
  • Nanoparticles for the use as pinning centers in superconductors
    Patent number: 10450199
    Abstract: The present invention is in the field of nanoparticles, their preparation and their use as pinning centers in superconductors. In particular the present invention relates to nanoparticles comprising an oxide of Sr, Ba, Y, La, Ti, Zr, Hf, Nb, or Ta, wherein the nanoparticles have a weight average diameter of 1 to 30 nm and wherein an organic compound of general formula (I), (II) or (III) or an organic compound containing at least two carboxylic acid groups on the surface of the nanoparticles (I) (II) (III) wherein a is 0 to 5, b and c are independent of each other 1 to 14, n is 1 to 5, f is 0 to 5, p and q are independent of each other 1 to 14, and e and f are independent of each other 0 to 12.
