Abstract
Abstract A method of continuously producing a super conductive intermetallic compound. It includes passing a filament of a metallic substrate through a high temperature plating chamber. The filament is heated electrically to a higher temperature while plating gases of the metals which make up the intermetallic compound are introduced in the form of halides of such metals along with sufficient hydrogen to complete a chemical change which plates the superconductor on the filament.

Claims Analysis

Claim 1
Independent Claim
129 words
Method of continuous production of a superior superconducting compound in wire form, comprising the steps of passing a filament of niobium wire substrate through a plating chamber, heating said wire filament in said plating chamber to a temperature of about 1,200° C. by generating a standing half wave of radio frequency current in a predetermined length of said wire and by simultaneously passing a DC electric current through said wire in said chamber, introducing gaseous germanium chloride and niobium chloride and hydrogen in relative amounts to produce optimum rate of plating of the super conductor compound niobium-germanium on said niobium substrate and introducing an inert gas to assist in temperature control, and passing said plated filament out of said chamber for freezing said compound in place on said filament.
