Integrated production of superconductor insulation for chemical vapor deposition of nickel carbonyl
This paper describes a process for use in fabrication of nickel suboxide insulation on a superconductor. It comprises: reacting essentially oxygen-free nickel powder with essentially oxygen-free carbon monoxide at a temperature of at least 50{degrees} C. to produce a nickel carbonyl; separating the nickel carbonyl from reaction by-products and excess reagents by cooling the carbonyl to 10{degrees}-43{degrees} C and decanting the nickel carbonyl liquor to produce a purified carbonyl; and at least periodically contacting the purified carbonyl to a surface of a wire containing superconductor or superconductor precursors in an atmosphere at least periodically containing a controlled amount of oxygen, with the wire being at a temperature of 50{degrees}-800{degrees}C to produce nickel suboxide insulation on the wire.
