Abstract: In preparing titanium nitride having a substantially uniform particle size of less than 1 m  by a single stage reaction of titanium tetrachloride vapours and anhydrous ammonia gas, one or both of the gases is preheated to a temperature between 300 DEG  and 1200 DEG  C. to produce a mixture of gases, irrespective of the heat of reaction, which would have a temperature not below 600 DEG  C., preferably not below 750 DEG  C.  The gases should be preheated to 700-900 DEG  C., and for a mean particle size TiN 0.25 m  or less, e.g. 0.10 m  the reaction temperature may be 650-1200 DEG  C., preferably 750-950 DEG C. 1-10 mols., preferably 2-4 mols. NH3 may be reacted with 1 mol. TiCl4.  The reaction chamber should be cylindrical with diameter at least 5 times and length at least 10 times the diameter of the TiCl4 feed orifice, if single, or of the maximum distance apart of the two outermost TiCl4 orifices, if a plurality are used.  The velocity of the gases in the orifices should correspond to Reynolds number below 2500.  The NH3 and TiCl4 may be fed in separately, through parallel ducting, or concentrically, along the axis of the chamber, at 2-20 m/sec. and the speed of the TiCl4 should exceed that of the NH3 by 500 per cent.  The diameter of the inner ducting may be 0.5-8 mm. and streamline gas flow should be obtained.  One or more concentric tube assembly burners may be used, the TiCl4 being introduced through the inner ducting through one or more cylindrical orifices having a length to diameter ratio at least 5:1 and a perimeter to cross-sectional area ratio not less than 5 cm.-1, e.g. 5-20 cm.-1 for an average particle size 0.25 m  and 20-80 cm.-1 for particle size 0.10 m .  The NH3 may be introduced through the annular space, confined between parallel concentric cylinders, of length at least 5 times the difference in diameter between the outer and inner cylinders, but may be less than 5 times, e.g. twice, when Reynolds number is 100-600.  The TiCl4 may alternatively be fed through the annular space.  The pressure in the reaction may be 0.1-10 atmos. The suspension of TiN in HCl, Cl2, &c., is cooled, e.g. by indirect cooling, by recirculation of cooled gases, by passage through an indirectly cooled fluidized bed, or by chilling with liquid TiCl4 on chlorine, and the TiN separated on cyclones or filters.  The TiN is cooled below 200 DEG  C. before air contact. The TiN may be washed with aqueous HCl and then with water to remove NH4Cl and TiCl4 or such absorbed material may be removed by heating in a current of N2 to 900 DEG  C. and cooling to 200 DEG  C. out of contact with air.
