Abstract
Manufacturing process of an electrically insulating and mechanically structuring sheath on an electric conductor which applies notably to the manufacture of superconducting magnets, wherein a ceramic precursor (4) in gel form is formed, then a coating of the conductor (2) with this precursor, and this coating is then heat treated to form the ceramic.

Manufacturing process of an electrically insulating and mechanically structuring sheath on an electric conductor, which comprises the stages of:
- formation of a ceramic precursor in gel form,
- formation of a coating of the conductor with the ceramic precursor in gel form, and
- heat treatment of the coating, thereby forming a ceramic from the ceramic precursor in gel form,
- wherein the ceramic precursor in gel form is formed from a liquid solution comprising water, a mineral component selected from the group consisting of boehmite and clays of the kaolin family, and an organic binding agent, wherein the mineral component is made to react with an acid to gel the solution, thereby forming the ceramic precursor in gel form.
