Self-propagating high-temperature synthesis of nano-sized titanium carbide powder

Abstract: The combustion process of a titanium-carbon system with sodium chloride as an inert diluent was investigated. The combustion laws and microstructure of final products according to diluent content were obtained. It was shown that sodium chloride not only decreases combustion temperature but also makes effective protective shells around primary carbide crystals and keeps this ultrafine structure up to the end of combustion. As a result, nano-sized titanium carbide powders were successfully obtained.

“…NaCl does not react with the product phases and does not form new or hard-to-leach phases, as opposed to MgO. The effect of NaCl has been investigated previously in other combustion synthesis systems [15,30,31]. When NaCl was used as the diluent, no crystalline compounds containing NaCl was detected in the products.…”

“…A high-frequency plasmatron with gas discharge stabilization was used to generate the plasma [12,13]. In connection with the high ionization potential of nitrogen in the plasma torch, an argon discharge is created by means of an electric pulse of high voltage from a tungsten ignition needle.…”

“…There are several theories of modification, but none of them describes the process completely. Nanodispersed compositions have been used as modifiers of steels and alloys [10][11][12][13]. The disadvantage of the work on the modification of structural steels and alloys with nanodispersed compositions is the lack of a comparative evaluation of different methods for obtaining nanocomposites and the thermodynamic analysis of the existence of nanoparticles in the melt.…”

“…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.…”
