Simple synthesis of nano-sized refractory metal carbides by combustion process

Evolution of structural and thermal properties of carbon-coated TaC nanopowder synthesized by single step reduction of Ta-ethoxide

“…Ta 2 O 5 and TaCl 5 have emerged as the most common precursors for the synthesis of TaC. These along with various carburization sources have been used for the synthesis of nano-TaC either in vacuum or inert atmosphere where the single phase TaC nano-particles are obtained only at temperatures greater than 1000 C. 4,[14][15][16][17][18][19][20][21] Addition of catalysts such as Mg, Ni 7,16 and/or halogenation agents such as NaF 16,20 can reduce the reduction temperature. Recent reports indicate that TaC can be synthesized using TaCl 5 precursor at temperature range of 600-900 C. 5,6,22 Use of organic precursors has mostly been limited to multistep processes involving formation of dispersed Ta 2 O 5 followed by carburization using an external carbon source.…”

Metal (Mo, W, Ti) Carbide Catalysts: Synthesis and Application as Alternative Catalysts for Dry Reforming of Hydrocarbons—A Review

“…Other methods of TiC production, which require a high energy input, are carbothermal reduction of TiO 2 [84][85][86], the plasma method [87], synthesis from elements [88], the self-propagating high-temperature method [89], chemical vapor deposition [90], and the magnesiothermic method [91,92]. The simplest, relatively inexpensive, most common, and most commercially used method is carbothermal reduction.…”

Synthesis of Titanium Carbide by Means of Pressureless Sintering

“…The magnesiotermic process is carried out in argon medium at high pressure to suppress magnesium evaporation. A feature of magnesiotermic method is the need for acid treatment of the products to remove magnesium oxide [13,14].…”
