Dynamic carbotermal 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.
