- Abstract
Dynamic carbothermal reduction-nitridation (DCRN) is a new approach developed to produce more effective ceramic powder production than classical static system of carbothermal reduction-nitridation (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 TiO2 and carbon black powders in the stoichiometric ratio (C/TiO2=2). TiN powders of sub-micron were obtained in a graphite reactor from the prepared granules under N2 gas flow. The effects of various test parameters were investigated for TiN synthesis, such as temperatures of reaction (1350-1450°C), reaction time (0.5-3 h), N2 gas flow rate (60-120 L/h) and reactor rotation speed (2-6 rpm). The phases and microstructures of the powders were characterized by XRD, SEM and FESEM analyses.
