Webnitride, any of a class of chemical compounds in which nitrogen is combined with an element of similar or lower electronegativity, such as boron, silicon, and most metals. Nitrides contain the nitride ion (N3−), and, similar to carbides, nitrides can be classified into three general categories: ionic, interstitial, and covalent. Certain metal nitrides are … WebThis method accurately accounts for the crystallographic characteristics of both structures under consideration. Its application is demonstrated in detail for the transition metal nitrides with NaCl structure. Calorimetric measurements in the metastable system (Ti, Al)N provide experimental refinement of the estimation method. Résumé
WebUsing a neutron diffraction structure analysis method it is found that an order-disorder phase transition of the first kind occurs in a nonstoichiometric niobium carbide NbCy at a temperature of ≈ 1300 K in the composition range NbC0,81-NbC0,88.
