Superconducting wires based on a yttrium ceramic
Abstract
A study was made of the fabrication of high temperature superconducting ceramic wires based on yttrium in various metallic shells. The shells used in the process were 10-mm-diameter thin-walled tubes of stainless steel (Kh18N10T), Nimonic alloy (Kh20N80), copper, and silver. Measurements of the critical current density is presented for the best specimens of round and rectangular cross sections. It is found that alloying of the yttrium ceramic by silver and gold makes it possible to double its current-carrying capacity.
