| Abstract: | Metal nitrides and carbides powders were synthesized by the spark discharge method in liquid ammonia at 100 °C and 11 kV of the spark discharge voltage and in n-heptane at 25 °C and 7.5 kV using the pellets of aluminum, titanium, iron and chromium as the starting material. The main products were AlN, TiN0.51,  -Fe,  -Cr2N in liquid ammonia, and Al4C3, TiC, -Fe, Fe2C and Cr7C3 in n-heptane. The agglomerated particle size decreased with increasing melting point of the metal used as the starting material. |
