Abstract
A method of the producing a ductile and stable particle superconductor, as well as the product itself, from particles of the formula NbN, NbN.sub.1-x C.sub.x where x is less than or equal to 0.5, Nb.sub.3 Al, Nb.sub.3 Si, Nb.sub.3 Ge, Nb.sub.3 Sn, V.sub.3 Ga or V.sub.3 Si from a reaction in a hydrogen plasma. The particles are incorporated into a metallic matix or coprecipitated with a metal powder.
