| Research Abstract |
Niobium nitride in rock salt type structure had been known as a superconductor with Tc=17K. New superconductors were obtained in niobium oxynitrides or nitride in ammonolyses either of homogeneously mixed amorphous oxides or ternary oxide as follows ; (1)rock salt type (Nb_<0.95>Mg_<0.05>)(N_<0.92>O_<0.08>), (Nb_<0.89>Al_<0.11>)(N_<0.84>O_<0.16>),(Nb_<0.87>Si_<0.09>□_<0.04>)(N_<0.87>O_<0.13>),(2)LiTa_3N_4 type (Li_<0.88>□_<0.12>)Nb_3(N_<0.87>O_<0.13>)_4,(3)platy crystals of rock salt type (Nb_<0.5>Ti_<0.5>)N
