Nitrides, Phosphides, Arsenides, and Related Compounds

Nitrides, Phosphides, Arsenides, and Related Compounds. The presence of imperfections in the metal sub-lattice of cubic tantalum nitride indicated by neutron diffraction experiments has been confirmed by density measurements the results are consistent with the stoicheiometry Tao.saN. The phase diagram of the Ta-N system has been investigated. The dissociation pressure of non-stoicheiometric niobium mononitride has been measured,and the structures of Nb32N3, Ni2Ta4N, TagN, and TaagNj have been determined. 

Co-condensation of Nb and N2 in an argon matrix produces a material whose i.r.
