Abstract
A method of coating products such as metallic coil formers and wire containing the components of an intermetallic superconductive compound in which the coating is flexible at room temperatures but which has good insulating properties after heat treatment, the coating comprising a mixture of sodium silicate, chalk and China clay which reacts on heat treatment to form an insulating ceramic but which is flexible when merely dried.
Claims8
A method of insulating an intermetallic compound superconducting wire product which comprises the steps of coating an intermetallic superconductor wire precursor with a coating from an aqueous mixture consisting essentially of sodium silicate, China clay and calcium carbonate, drying the coated wire precursor after coating and winding the dried wire precursor around a former, heating the wire and former to form an insulating ceramic from the coating and reacting the components of the intermetallic compound in the precursor to form the intermetallic superconducting compound in the wire.
