| 1 | High-entropy perovskite RETa_(3)O_(9) ceramics for high-temperature environmental/thermal barrier coatings显示文摘Four high-entropy perovskite(HEP)RETa_(3)O_(9) samples were fabricated via a spark plasma sintering(SPS)method,and the corresponding thermophysical properties and underlying mechanisms were investigated for environmental/thermal barrier coating(E/TBC)applications.The prepared samples maintained low thermal conductivity(1.50 W·m^(−1)·K^(−1)),high hardness(10 GPa),and an appropriate Young’s modulus(180 GPa),while the fracture toughness increased to 2.5 MPa·m^(1/2).Nanoindentation results showed the HEP ceramics had excellent mechanical properties and good component homogeneity.We analysed the influence of different parameters(the disorder parameters of the electronegativity,ionic radius,and atomic mass,as well as the tolerance factor)of A-site atoms on the thermal conductivity.Enhanced thermal expansion coefficients,combined with a high melting point and extraordinary phase stability,expanded the applications of the HEP RETa_(3)O_(9).The results of this study had motivated a follow-up study on tantalate high-entropy ceramics with desirable properties. | Lin CHEN Baihui LI Jun GUO Yuke ZHU Jing FENG | 2022 | Journal of Advanced Ceramics2022，11，4： | 4 |

| 3 | Simultaneous manipulations of thermal expansion and conductivity in symbiotic ScTaO_(4)/SmTaO_(4) composites via multiscale effects显示文摘Effective manipulations of thermal expansion and conductivity are significant for improving operational performances of protective coatings,thermoelectric,and radiators.This work uncovers determinant mechanisms of the thermal expansion and conductivity of symbiotic ScTaO_(4)/SmTaO_(4) composites as thermal/environmental barrier coatings(T/EBCs),and we consider the effects of interface stress and thermal resistance.The weak bonding and interface stress among composite grains manipulate coefficient of thermal expansion(CTE)stretching from 6.4×10^(−6) to 10.7×10^(−6) K^(−1) at 1300℃,which gets close to that of substrates in T/EBC systems.The multiscale effects,including phonon scattering at the interface,mitigation of the phonon speed(vp),and lattice point defects,synergistically depress phonon thermal transports,and we estimate the proportions of different parts.The interface thermal resistance(R)reduces the thermal conductivity(k)by depressing phonon speed and scattering phonons because of different acoustic properties and weak bonding between symbiotic ScTaO_(4) and SmTaO_(4) ceramics in the composites.This study proves that CTE of tantalates can be artificially regulated to match those of different substrates to expand their applications,and the uncovered multiscale effects can be used to manipulate thermal transports of various materials. | Lin Chen Jiankun Wang Baihui Li Keren Luo Jing Feng | 2023 | Journal of Advanced Ceramics2023，12，8： | 0 |

| 5 | Mechanical property enhancements and amorphous thermal transports of ordered weberite-type RE_(3)Nb/TaO_(7) high-entropy oxides显示文摘A_(3)BO_(7)-type(A=rare earth(RE),B=Nb or Ta)oxides have been studied as protective coating materials because of their low thermal conductivity;however,their hardness,toughness,and stiffness are insufficient,particularly for members with webeirte-type structures.In this work,we have synthesized two high-entropy oxides(HEOs)of weberite-type RE niobates/tantalates(RE_(3)Nb/TaO_(7)),i.e.,(Nd_(1/7)Sm_(1/7)Eu_(1/7)Gd_(1/7)Dy_(1/7)Ho_(1/7)Er_(1/7))_(3)NbO_(7)(7HEOs-Nb)and(Nd_(1/7)Sm_(1/7)Eu_(1/7)Gd_(1/7)Dy_(1/7)Ho_(1/7)Er_(1/7))3(Nb_(1/2)Ta_(1/2))O_(7)(7HEOs-NbTa),to overcome the mechanical deficiencies.The short-and long-range ordered arrangements of RE cations in the A-site and Nb/Ta cations in the B-site were identified by the X-ray diffraction(XRD),scanning electron microscopy equipped with energy-dispersive spectrometry(EDS),and transmission electron microscopy.The enhancements in hardness(H=9.4 GPa)and fracture toughness(KIC=2.0 MPa·m^(1/2))were realized by grain refinement,solid solution strengthening,and high stiffness(K).The exceptional phase stability at 25-1500℃,amorphous thermal conductivity(k=1.5-1.7 W·m^(−1)·K^(−1) at 25-900℃),and high thermal expansion coefficients(TEC>11.0×10^(−6) K^(−1) at 1500℃)further supported their potential application as protective coating materials. | Lin CHEN Keren LUO Baihui LI Mingyu HU Jing FENG | 2023 | Journal of Advanced Ceramics2023，12，2： | 0 |
