Research on the Synthesis of Titanium Nitride by Carbothermal Reduction Nitriding with Anatase and Flake Graphite

Abstract:

Using anatase and flake graphite as starting material, titanium nitride was prepared by carbothermal reduction nitriding method under nitrogen gas pressure 0.05 MPa and flow rate 0.3 m³/h, at 1673K(1400°C).The proportion of n_c and n_TiO2 are 1.5:1,2.0:1,2.2:1 and 2.5:1. The phase composition and microstructure of titanium nitride were investigated by XRD and SEM. The results show that: titanium nitride can be prepared with anatase and flake graphite by carbothermal reduction nitriding method. When the proportion of n_c and n_TiO2 is 2.2:1 the quantity of titanium nitride is the most. Because the reacting temperature is low and the contact area of the anatase and flake graphite is small the large grain size and uniform grain size titanium nitride can not be obtained.
