A novel defect fluorite type high-entropy (Dy0.2Ho0.2Er0.2Tm0.2Lu0.2)2Hf2O7 ceramic with low thermal conductivity and CTE: a mechanism study

A novel defect fluorite type high-entropy (Dy0.2Ho0.2Er0.2Tm0.2Lu0.2)2Hf2O7 ceramic with low thermal conductivity and CTE: a mechanism study

The “seesaw relationship” between thermal conductivity and thermal expansion coefficient (CTE) in most high temperature ceramics has become an obstacle to the design of long-life multilayer thermal/environmental barrier coatings (T/EBC). Due to low thermal conductivity and CTE, defect fluorite type...
