摘要	(Ho1/4Er1/4Yb1/4Lu1/4)2SiO5 is synthesized and characterized for the application of a promising multifunctional thermal and environmental barrier coating (TEBC) material. X-ray diffraction and scanning electron microscopy analysis indicate that a X2-type multiple-RE silicate (4RE1/4)2SiO5 is formed with homogeneous distribution of the four rare earth species. Dense bulk sample exhibits excellent phase stability up to 1400 degrees C. Key properties including Young's modulus, thermal conductivity and thermal expansion coefficient show interesting compo-sition effects. Specially, (Ho1/4Er1/4Yb1/4Lu1/4)2SiO5 demonstrates higher elastic stiffness, lower thermal con-ductivity, lower thermal expansion coefficient and good resistances to molten CMAS and water vapor corrosions. These results confirm the strategy of multiple-RE engineering that may provide optimal property of advanced TEBCs.
