Obtaining the Nanostructured Nitride Composition TiN-BN Powder by the Self-Propagating High-Temperature Synthesis from the Azide KBF₄-NaN₃-Na₂TiF₆ and "NH₄BF₄-NaN₃-Na₂TiF₆ Systems

Abstract:

This paper presents the results of a study on the preparation of nanostructured nitride composition TiN-BN in the boron halide - sodium azide - titanium halide system by the azide SHS technology. SHS-Az technology makes it possible to produce powders having the desired properties, only in one step, without blending separately prepared powders of titanium nitride and boron nitride, and to obtain the final product in the form of micro-and nanosized powder nitride compositions TiN-BN by using complex halides of titanium and boron. Thus, the composite powder TiN and BN obtained from the KBF₄-NaN₃-Na₂TiF₆» and «NH₄BF₄-NaN₃-Na₂TiF₆ systems can be classified as a nanostructured powder (nanopowder).
