and their phase structure and thermal physical properties were tested. It is found that the modified(Sm
ceramic material has a cubic pyrochlore structure. Due to the change of mass difference and radius difference
phonon scattering increases
average free path decreases
and thermal conductivity decreases. At 600 ℃
the thermal conductivity of (Sm
is 1.3 W/(m·K). The co-doping of Yb
can effectively reduce the thermal diffusivity and thermal conductivity (RT–1000 ℃ ) of ceramic materials
which can be used as candidate materials for thermal barrier coatings.
