摘要
Herein, a series of chalcogen-containing MAX phases, Hf2(SexS1_x)C, were successfully synthesized, whose lattice parameter change follows the Vegard's law. The average coefficient of thermal expansion (CTE) can be continuously tuned from 7.59 mu K_ 1 to 9.93 mu K_ 1 when the occupancy rate x of Se changes from 0 to 1. The substitution of Se for S effectively soften the crystal structures that is reflected by long average M-A bond in Sealloying Hf2(SexS1_x)C. However, the CTEs along a and c axes in all Hf2(SexS1_ x)C MAX phases are almost same which may be find application in thermal barrier coating (TBC) that isotropic volume change is highly demanding.
