“…[1][2][3][4] Until now, several methods have been developed for the synthesis of ZrC including carbothermal reduction, 5 chemical vapor deposition, 6 self-propagating high-temperature synthesis, 7 mechanochemically activated synthesis, 8 laser pyrolysis, 9 wire explosion, 10 electrospinning, 11 and sol-gel based method. It has a high melting point, solid-state phase stability, low evaporation rate, good thermal shock resistance, high hardness, high modulus of elasticity, high corrosion and wear resistance, high thermal, and electrical conductivity.…”

In this study, a novel method for the synthesis of fine ZrC powder was presented. It consists of chemical vapor deposition (CVD) of C from CH4 on ZrO2 particles followed by carbothermal reaction. Firstly, optimal CVD conditions (1300 K and 30 minutes) yielding the stoichiometric amount of C deposit (23 wt%) were determined. Carbothermal reaction behavior of the carbon‐coated oxide particles was then investigated in Ar flow at 1700‐1800 K for 0‐120 minutes. Mass measurements, XRD and SEM techniques were used to characterize the products at various stages of the process. Lattice constants and mass losses of the samples increased to the levels of ZrC with increasing temperature and time. Almost pure ZrC powder (oxygen content: 0.59 wt%) with a mean particle size of ~170 nm was synthesized at 1800 K within 120 minutes. The present study demonstrates that ZrC powder can be synthesized at lower temperatures and shorter reaction times using C‐coated ZrO2 powders compared with the conventional method which uses a mixture of ZrO2 and solid C particles.

“…Many routes were developed to synthesize powders -Selfpropagated High-temperature Synthesis (SHS) reaction, [5][6][7][8] laser pyrolysis, [9][10][11][12][13] fusion synthesis by arc-melting, 14 mechanosynthesis [15][16][17] or thin films by Chemical Vapour Deposition (CVD 18,19 ). Each of these synthesis routes presents both advantages and drawbacks, but they are generally used to produce limited quantities of carbides.…”

“…Reaction of carbothermal reduction of zircon is strongly dependent on the amount of added carbon [2,7,[23][24][25][26][27], i.e. by varying the C/ZrSiO 4 ratio, it is possible to obtain ZrO 2 , ZrO 2 /SiC or ZrC/SiC as reaction products:…”
