Titanium carbide, predominantly in the form of submicron small cubic crystals, is formed by reacting, in the vapor state, titanium halide, reducing agent and carbon source at carbideforming temperatures. High surface area titanium carbide is produced by establishing a stream of hot hydrogen and introducing titanium halide into said hydrogen stream at a point upstream of the point at which the carbon source is introduced into the hydrogen stream. When the order of introduction is reversed, the titanium carbide product surface area decreases. |
