Thermodynamic model of high-temperature synthesis of oxygen-free titanium compounds from titanium tetrachloride

Abstract

Technological characteristics and equilibrium energy of plasma synthesis for titanium nitride, carbide and carbonitride-final product output and composition, energy consumption, plasma enthalpy required are calculated for the reactions:-TiCl4 + x H2 + y N2 (TiN synthesis);-TiCl4 + x H2 + z CmHn (TiC synthesis);-TiCl4 + x H2 + y1 N2 + z1 CmHn (TiCN synthesis). Calculations are carried out in the temperature range of 500-4000 K at the total pressure in system of 0.1 MPa and in the range of reagents ratio of: x = 8

Sintering Behavior and Microstructure of TiC-Me Composite Powder Prepared by SHS

“…Therefore, oxygen and nitrogen pose great difficulties in obtaining pure TiC. Production of titanium carbide with the self-propagating high-temperature synthesis (SHS) method is characterized by the fact that the combustion reaction in the compact of titanium powder and carbon black completes in just a few seconds [11][12][13][14][15][16][17][18]. The synthesis is most often carried out in a protective inert atmosphere.…”
