Abstract

The processing of In₂O₃-ZrO₂ and SnO₂-ZrO₂ coatings were evaluated on Nb₃Sn wires. Coatings were produced by using reel-to-reel, continuous sol-gel system from solutions of Zr, In, and Sn based organometallic compounds. Microstructure, phase composition and formation of the coatings were characterized by means of ESEM, SEM, EDS, XRD and DTA studies. Sol-gel zirconia based ceramic coatings, varying from submicron to several of microns in thickness, have been successfully applied to Nb₃Sn wires at the National High Magnetic Field Laboratory. Insulated and uninsulated Nb₃Sn conductors, that were heat treated together, showed about the same J_c.
