The reaction between titanium pellet and flowing nitrogen under 1 atm over the temperature range 973 to 1373 K was investigated by thermogravimetric analysis system, scanning electron microscope and X-ray diffractometer. α-Ti → TiN0.3 → TiN0.5 → TiN was found to be the sequence of transformation of solid sample. Experimental results indicated that the reaction rate could be increased by increasing the gas flow rate, nitrogen concentration or reaction temperature. The rate was also found to be increased by decreasing the thickness of titanium pellet. The smaller the titanium grain, the faster the reaction. The effect of forming pressure of pellet on the reaction rate was found to be insignificant. Effects of additives such as Al, B, Fe, Si, TiN and Y2O3 were found to be negative on the reaction rate. Empirical expression of conversion of titanium has been determined.
