Abstract

The high⁃entropy strategy was explored by incorporating tetravalent elements through a solid⁃state reaction method to effectively enhance the thermophysical and mechanical properties of aluminosilicate ceramics.Four high⁃entropy aluminosilicate ceramics with different configurational entropies were successfully synthesized：0.25（Y1/2Yb1/2）4Al2O9·0.75（Y1/2Yb1/2）2（xMe1/x ）2O7（x=1，2，3，4；Me=Si，Zr，Ti，Ce）.These ceramics were systematically studied including phase composition，microstructure，thermophysical properties，and mechanical properties.The results indicated that the coefficient of thermal expansion（CTE） of the ceramic samples was gradually increased with the increase of configurational entropy.While the thermal conductivity was decreased significantly.Notably，the sample with the highest configurational entropy exhibited a thermal conductivity as low as 0.6 W/（m·℃），whereas its CTE reached 5.27×10⁻⁶ ℃-1.In terms of mechanical properties，although the elastic modulus was decreased for the increase of entropy，both hardness and fracture toughness were markedly enhanced.Specifically，the fracture toughness achieved 2.2 MPa·m1/2，and the Vickers hardness was measured at 8.5 GPa.Microstructural characterization revealed that grain refinement was effectively contributed to the improvement of mechanical properties.This study presented a novel approach for tailoring the thermophysical and mechanical properties of aluminosilicate ceramics and verified the significant potential of the high⁃entropy strategy in the domain of advanced ceramic materials.
