Abstract :Dynamic carbotermal reduction-nitridation insert ignore into journalissuearticles values(DCRN); is a new approach developed to produce more effective ceramic powder production than classical static system of carbothermal reduction-nitridation insert ignore into journalissuearticles values(CRN); method. In this new technique of DCRN, powder is produced in a moving system and production takes place at relatively lower temperatures and/or shorter times than CRN method. This study examines production of TiN powder by the DCRN method. The granules were prepared using TiO 2 and carbon black powders in the stoichiometric ratio insert ignore into journalissuearticles values(C/TiO 2 =2);. TiN powders of sub-micron were obtained in a graphite reactor from the prepared granules under N 2 gas flow. The effects of various test parameters were investigated for TiN synthesis, such as temperatures of reaction insert ignore into journalissuearticles values(1350-1450°C);, reaction time insert ignore into journalissuearticles values(0.5-3 h);, N 2 gas flow rate insert ignore into journalissuearticles values(60-120 L/h); and reactor rotation speed insert ignore into journalissuearticles values(2-6 rpm);. The phases and microstructures of the powders were characterized by XRD, SEM and FESEM analyses.
