Abstract: | Titanium nitride powders were synthesized by the spark-discharge method in liquid ammonia at — 78 to 130 °C and 3.5–10.5 kV discharge voltage using titanium pellets as the starting materials. Titanium nitride possessing nitrogen defect, TiN1–x(x0.5), was obtained as the main product, together with small amounts of -Ti alloyed with nitrogen. The increase in temperature of the liquid ammonia resulted in an increase in the titanium nitride content in the product but a decrease in the powder production rate. By calcining the mixed powders of TiN1–xand -Ti in a nitrogen atmosphere around 1200 °C, stoichiometric TiN was obtained as single phase. |
