“…It was assumed, that by carrying out the simultaneous synthesis of the components a better homogenization will be obtained. In general, the studies concerned the synthesis of transition metal carbides in multistage processes, involving nanometric reagents [2][3][4][5][6].…”

“…No systematic study of reduction of these oxides in nitrogen-containing gas atmosphere was found in literature, although reduction of rutile in nitrogen was reported. 10,11,[18][19][20][21][22][23][24][25] This paper investigates the carbothermal reduction of ilmenites of different grades and synthetic rutile in the H2-N2 gas mixture and pure nitrogen at different temperatures. Ilmenites of different grades contain different amounts of iron and titanium oxides.…”

“…Besides commercialized carbothermal reduction method, 5),6) several other processes have been proposed for the production of TiCN powders such as the direct solid reaction of TiC with TiN or Ti with C, N, 7),8) the self propagating high-temperature synthesis (SHS), 9) the gaseous phase reaction 10) and the liquid phase reaction such as the sol-gel process, and so on. 11) However, these processes have at least one or more of the following drawbacks: (1) coarse particle formation owing to a very high temperature reactions (2073 K-2273 K), (2) easy oxidation during the process resulting in formation of TiCxOy, (3) high free carbon content and contamination, in particular, during the milling process and (4) need for initial titanium powder of high purity.…”
