Conclusions

Niobium nitride produced by nitriding niobium wire is brittle, which makes it unsuitable for many practical applications. By comparison, nitride specimens produced by nitriding niobium powder compacts of 20% porosity (treatment under a nitrogen pressure of 5 atm for 3 h at 1400°C) seem to hold considerable promise. The superconducting characteristics attainable with such specimens are Tc=15.4°K and ΔT= 0.1°K.
