ABSTRACT:
A method of forming a superconductive joint between superconductors made of filaments of superconducting material embedded in a matrix material utilizes two baths of molten metals. One of the baths of molten metal is used for etching the matrix material away from the superconducting filaments and is vibrated at an ultrasonic frequency. The other bath is also vibrated at an ultrasonic frequency and is used to mold the etched superconductors into a superconducting joint. Superconducting joints may thereby be made under ordinary atmospheric conditions between superconducting wires having similar and/or different matrix materials.
