Abstract Ceramic fibers are potential lightweight materials for high‐temperature insulation due to their excellent stability and low thermal conductivity. However, the grain growth at high temperatures leads loss of flexibility decreases in performances ceramic fibers. Herein, we prepared flexible (La 0.2 Nd Sm Gd Yb ) 2 Zr O 7 (LNSGY) high‐entropy nanofibrous membranes using polyacetylacetone rare‐earth zirconium precursors by electrospinning method. According XRD TEM analyses, LNSGY...
SrTiO3-based oxides have been investigated as a promising n-type thermoelectric material at high temperatures; however, the relatively thermal conductivity results in inferior performance. The lattice can be significantly reduced by high-entropy engineering via severe distortion. However, configuration entropy also causes deterioration of carrier mobility and restrains electron transport resulting low electrical conductivity. In this work, 1.7 W/(m·K) 1 073 K improved 112 S/cm from 60...
Thermoelectric materials have gained wide attention to realize multilevel efficient energy management alleviate the increasingly severe crisis. Oxide ceramics were well-explored as potential thermoelectric candidates because of their outstanding merits, including abundance, eco-friendliness, high-temperature stability, and chemical stability. In this work, we aim provide a comprehensive summary diversified state-of-the-art oxide establish links between composition designing, preparation...
Abstract For thermoelectric applications at high temperatures, perovskite SrTiO 3 is a promising contender as an n‐type oxide (TE) material. In this work, Sr x La 0.1 TiO 3− δ /TiO 2− y composite ceramics were successfully synthesized by solid state reaction, using combination of A‐site cation vacancy and fabrication. Through X‐ray diffractometer scanning electron microscopy analysis, complex microstructure composed two kinds titanium oxides was formed after reductive sintering annealing....
Misfit-layered Ca3Co4O9 as a p-type semiconductor is difficult to commercialize because of its relatively poor performance. Here, Ca2.7-xLaxAg0.3Co4O9/Ag composites prepared by spark plasma sintering were systematically investigated in terms La3+ dopant levels and nano-sized Ag compacts. Multiscale microstructures stacking fault, dislocation, oxygen vacancy-linked defects could be recognized an effective strategy for tuning the transport charge carriers phonon scattering. An increasing...
Abstract Inspired by the concept of entropy stabilization, a series rare‐earth‐zirconate medium‐entropy ceramics were designed. The influence size disorder parameter on mechanical and thermophysical properties was investigated. results show that prepared exhibit single pyrochlore structure, lattice constant is linearly related to average doped rare‐earth ionic radius. scanning electron microscope‐energy‐dispersive spectroscopy indicate uniform distribution elements. have relative density...
α-SiAlON is a potential wave-transmittance material for radome materials, yet the comprehensive properties need to be improved. In this study, series of SrxY0.5-xSi12-(m+ n) Alm+nOnN16-n (x = 0.02, 0.04, 0.06, and 0.08) porous ceramics with porosities ranging from 44.15% 58.62% were synthesized via tert-butanol gel-casting. The real part permittivity was in range 3.13–4.18 (8.2–12.4 GHz) over 70% wave transmittance thickness 5.5–9.5 mm. thermal conductivity flexural strength ranges...
Two-dimensional perovskite microplatelets have played an important role in various applications, especially acting as a template to guide grains' epitaxial growth the preparation of textured ceramics. The (001) oriented Sr0.9La0.1TiO3 with high aspect ratio ∼20 were synthesized and obtained from Aurivillius Bi4Ti3O12 precursors. To reveal mechanism topochemical microcrystal conversion Sr0.9La0.1TiO3, reaction interface, morphology development, phase composition evolution investigated. When...
