Atmospheric-Pressure Synthesis of Titanium Carbide in an Arc Plasma Reactor

— This paper reports on titanium carbide synthesis in an atmospheric-pressure arc plasma reactor by exposing a stoichiometric starting mixture (Ti : C ~ 1 : 1.05) to a plasma jet. The phase composition of the synthesized TiC powder has been determined as a function of the time during which the start...

Description
Summary:— This paper reports on titanium carbide synthesis in an atmospheric-pressure arc plasma reactor by exposing a stoichiometric starting mixture (Ti : C ~ 1 : 1.05) to a plasma jet. The phase composition of the synthesized TiC powder has been determined as a function of the time during which the starting mixture was exposed to a thermal plasma flow and the current (40–120 A) through the electric arc plasma source. The powders obtained under optimal conditions consist of the cubic titanium carbide phase and have a broad particle size distribution, with distinct agglomerates on the order of 50–100 μm in size. It is worth noting that the surface of the agglomerates has the form of a densified perforated crust (with a pore diameter no greater that 2 μm).
