中文摘要	Thermal expansion coefficient (TEC) is one of the most concerned properties for thermal barrier coating (TBC) materials. To enhance thermal expansion coefficient, a series of rare-earth zirconates Sm/sub 2/Zr/sub 2/O/sub 7/ with various contents of MgO were investigated. The samples were synthesized by solid state reaction at 1600 degrees C for 10h. And the thermal expansion coefficients of the samples were measured. The results showed that all the doping samples had higher expansion coefficients than pure Sm/sub 2/Zr/sub 2/O/sub 7/. Moreover, compared with the data reported of 8YSZ, ~15% enhancement had been achieved above 300 degrees C.
