Abstract
A method is disclosed for the production of superconductors consisting of a polymer or glass matrix which contains a very fine dispersion of superconducting particles, approximately 50 to 100 A in diameter, of intermetallic compounds of vanadium or niobium with the elements aluminum, germanium, silicon, gallium or tin, or of niobium nitride or niobium carbonitride. The matrix material is first brought into a viscous state and the superconducting particles are admixed with the viscous matrix in such quantities that, after solidification of the matrix, the particles are spaced at an average distance of 10 to 100 A. The superconducting material may be then formed in wires, filaments and tapes.
Claims18
A method for the production of superconductors consisting of a polymer or glass matrix with incorporated finely dispersed superconducting particles, about 50 to 1000 A in diameter, of intermetallic compounds of vanadium or niobium with the elements of aluminium, germanium, silicon, gallium or tin or of niobium nitride or niobium carbonitride, comprising the steps of:
- (a) converting the matrix material into a viscous state;
- and (b) admixing superconducting particles to this viscous matrix in such quantities that after solidification of the matrix material the incorporated particles are spaced at a mean distance of the order of 10 to 100 A.
A method for producing filaments, film or strip from a superconducting material comprising the steps of converting the matrix material with incorporated superconducting particles into a viscous state, and forming filaments, films or strip from this mass and subsequently solidified by cooling or drying processes.
