Tantalum pentoxide (Ta2O5) has attracted intensive attention due to their excellent physicochemical properties.Ta2O5 films were synthesized via electron beam evaporation (EBE) and subsequently annealed at different temperatures ranging from 300 to 900 ℃.X
Multi-component solid solutions with non-stoichiometric compositions are characteristics of ultra-high temperature carbides as promising materials for hypersonic vehicles.However,for groupⅣ transition-metal carbides,the oxidation behavior of multi-compone
The SiBCN matrix via chemical vapor infiltration (CVI) or/and polymer infiltration pyrolysis(PIP) technologies was orderly introduced to SiCf/SiC composites to optimize the mechanical property and electromagnetic (EM) shielding effectiveness simultaneousl
Ce2[Zr1-x(Mg1/3Sb2/3)x]3(MoO4)9 (0.02 ≤ x ≤ 0.10) ceramics were prepared by the traditional solid-state method.A single phase,belonging to the space group ofR(3)c,was detected by using X-ray diffraction at the sintering temperatures ranging from 700 to 85
In this study,the chemical precipitation coating (CP) process was creatively integrated with DLP-stereolithography based 3D printing for refining and homogenizing the microstructure of 3D printed Al2O3 ceramic.Based on this novel approach,Al2O3 powder was
(1-x)K0.5Na0.5NbO3-xBi(Zn2/3Nb1/3)O3 ((1-x)KNN-xBZN,x =0.010,0.015,0.020,0.025,and 0.030) lead-free ceramics were fabricated via a traditional solid-state method.The crystal structure,microstructure,dielectric,and conductivity behavior of this system were
Novel scheelite structures of Li2Ca(WO4)2,Li2Ca2(WO4)(SiO4),and LiCa2(WO4)(PO4)fluorescent materials were successfully prepared using a high-temperature solid-phase process.The compounds were characterized by X-ray diffraction and energy dispersive spectr
It is a very difficult work to sinter K0.5Na0.5NbO3 (KNN)-based materials with good reduction resistance in strong reducing atmosphere.0.945K0.48Na0.52Nb0.96Ta0.04O30.055BaZrO3 +0.03ZrO2 + y mol%MnO (KNNT-0.055BZ + 0.03Zr + yMn) ceramics sintered in reduc
