Abstract

Production of superconducting fiber bundles where in a CVD reactor niobium carbonitride of the general formula NbC.sub.x N.sub.y is deposited on support fibers by means of chemical deposition from the vapor phase by reaction of niobium chloride, carbon and nitrogen compounds, and in addition to the mentioned reaction gases at least one oxygen-containing gas is introduced into the CVD reactor in a controlled manner.
