Application of nanofibrous carbon for obtaining finely dispersed titanium carbide

Thermodynamic Analysis of the Chemical Reaction of Carbidation of Titanium Dioxide With Calcium Carbide and Calcium

“…At the same time, it was found that calcium carbide can be used as a carbon source for titanium carbide in the reaction (6). According to the thermodynamic analysis performed for the reaction (8) in the case where pure calcium is not involved in the chemical reaction, It was found that titanium dioxide is not regenerated by CaC3 -calcium carbide, and as a result, the reaction (8) does not occur at all.…”

“…The use of oxide powders of these metals in the production of pure metal powders in carburizing technology has a positive effect on the economic efficiency in the production of hard alloys and refractory materials [4][5][6]. Carbon powder (soot) is used to obtain tungsten or titanium carbide directly from tungsten or titanium oxide [7][8]. In this case, carbides can be obtained directly from the metal oxide, but in order to carry out the carbidization reaction, it is necessary to heat the reaction mixture to high temperatures of 1500-2000 °C.…”

“…In this case, carbides can be obtained directly from the metal oxide, but in order to carry out the carbidization reaction, it is necessary to heat the reaction mixture to high temperatures of 1500-2000 °C. That has a negative effect on the economic efficiency of the technology of direct carburizing of oxides of transition metals with carbon [8].…”
