Ultrahigh energy-storage performance of dielectric ceramic capacitors is generally achieved under high electric fields (HEFs). However, the HEFs strongly limit miniaturization, integration, and lifetime capacitors. Thus, it necessary to develop new materials with excellent densities moderate (MEFs). Herein, antiferroelectric material Ag0.9Ca0.05NbO3 (ACN) was used modify relaxor ferroelectric 0.6Na0.5Bi0.5TiO3-0.4Sr0.7Bi0.2TiO3 (NBT-SBT). The introduction ACN results in polarization...
(1− x ) BaTiO 3 – BiYO [(1− BT BY ] polycrystalline ceramics were prepared by solid‐state reaction method. The are in tetragonal phase when ≤ 0.04, transform to pseudocubic at ≥ 0.06, showing a classic ferroelectric relaxor transition = where the temperature was found shift higher with increasing frequency. dielectric permittivity peaks analyzed modified Curie–Weiss law. Both parameters ΔT diffuse and increase content, demonstrating stronger characteristic.
Bi0.5Na0.5TiO3-BaTiO3 (BNT-BT)-based ternary solid solutions were investigated for high-temperature capacitor applications. Through a comprehensive investigation of the (1 - x )(0.92Bi0.5Na0.5TiO3-0.08BaTiO3)- NaNbO3 [(1 )(BNT-BT)- NN, = 0 -0.45] system, 0.85(BNT-BT)-0.15NN was selected as parent matrix due to its relatively high permittivity (>1800) and favorable energy-storage density (0.56 J/cm3 at 7 kV/mm). The effect bismuth substitution on dielectric properties further characterized....
Abstract Carbon-phenolic (C-Ph) composites are typical ablative thermal protection materials. Excellent ablation and insulation performance indicate a decreased thickness of the shield. Thus, ZrSi 2 particles were introduced to improve low-density C-Ph composite. An oxyacetylene flame torch was used examine insulating characteristics. The curing process matrix resin not affected by . conductivities with different contents ranged from 0.219 ∼ 0.254 W K −1 ·m A continuous but very compact...
High electrochemically active manganese dioxide (MnO2) has been deemed to be a promising material for high mass loading electrode. Here, an amorphous MnOx nanostructure constituted by ultrafine nanoparticles was fabricated simple, controllable, and cost-effective strategy. The electrochemical properties of the as-prepared nanostructures were significantly improved due their crystalline structure. For electrode, optimized content MnOx, carbon black, nanotubes measured 79.1%, 13.5%, 7.4%,...

The corresponding lead-free ceramics obtained at the optimal sintering temperature. For ? material formed dense, homogeneous pseudocubic perovskite structures. increase of BMN content induces strong relaxor behaviours with diffuse phase transition characteristics, enhancing temperature stability dielectric properties....
