This patent describes a process for the production of superconducting fiber bundles which comprises, depositing niobium carbonitride of the general formula NbC/sub x/N/sub y/ wherein x+yless than or equal to1, on support fibers in a CVD reactor by means of chemical deposition from the vapor phase by reaction of niobium chloride, carbon and nitrogen compounds and in addition to the mentioned reactants introducing water vapor into the CVD reactor and regulating the amount of water vapor introduced into the CVD reactor to adjust the composition of the reaction gases such that the water vapor is between 0.15% and 8% by volume of the reaction gases to effect improvement of the superconduction properties of current carrying capacity and critical magnetic field strength of the niobium carbonitride deposited on the support fibers.
