Synthesis of high-entropy carbides from multi-metal polymer precursors

Preparation of (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)C high‐entropy ceramic nanopowders via liquid‐phase precursor

“…The mechanical properties and high-temperature oxidation resistance of high-entropy ceramics prepared by such transition metal carbides are better than those of single-component ceramics, and they have good application prospects. [10][11][12][13] The preparation methods of high-entropy carbide ceramics are mainly divided into solid-phase reaction method, [14][15][16] liquid-phase reaction method, [17][18][19] in-situ reaction melting infiltration method, 20 and arc melting method. 21 Among them, the solid-phase reaction method mainly includes the mechanical alloy method, 14 carbothermal reduction method, 15 and magnesium thermal reduction method.…”

“…21 Among them, the solid-phase reaction method mainly includes the mechanical alloy method, 14 carbothermal reduction method, 15 and magnesium thermal reduction method. 16 Precursor pyrolysis 17 and sol-gel methods 19 are the main applications of liquid-phase reaction methods. Currently, mechanical mixing of solids and high-temperature sintering are the main methods for preparing high-entropy ceramics.…”
