In this work, titanium carbonitrides were synthesized by self-propagating high-temperature synthesis (SHS) in nitrogen. For the first time, the synthesis of titanium carbonitrides by combustion was realized in nitrogen at atmospheric pressure. The synthesis was carried out by subjecting high-energy ball-milled titanium-carbon black powder mixtures to combustion in a nitrogen atmosphere. The influence of the ball milling time on the phase composition of the products of SHS conducted in the Ti+0.3C reaction mixture was studied. It was found that the titanium-carbon black mixtures need to be milled for a certain period of time for the combustion synthesis to yield a single-phase carbonitride product.
在本工作中，通过在氮气中进行自蔓延高温合成（SHS）制备了碳氮化钛。首次在常压氮气中通过燃烧实现了碳氮化钛的合成。合成过程是将高能球磨的钛-炭黑粉混合物在氮气气氛中进行燃烧。研究了球磨时间对在Ti + 0.3C反应混合物中进行的SHS产物相组成的影响。发现钛-炭黑混合物需要研磨一定时间，以便燃烧合成产生单相碳氮化物产物。
