Abstract A simple oxidation synthesis route was developed for producing magnetite nanoparticles with controlled size and morphology. Investigation of process the produced (NP) performed after under different temperatures. The phase transformation synthetic into maghemite and, henceforth, to hematite at temperatures dry has been studied. natural particles were directly transformed comparatively lower temperature, thus, bypassed. structures, morphologies particle sizes magnetic have...
Ceramics-based capacitors with excellent energy storage characteristics, fast charging/discharge rate, and high efficiency have received significant attention. In this work, [Formula: see text][Formula: text]NbO 3 (NBN) ceramics were processed through solid-state sintering route. The investigated crystallized in a single perovskite phase. Dense microstructure, small average grain size ([Formula: text]0.92 text]m) is obtained for the ceramics. A dielectric constant text]1000 accompanied by...
Relaxor-ferroelectric ceramics capacitors have been in the front line of investigations aimed at optimizing energy density due to their high <italic>P</italic><sub>max</sub>, suppressed <italic>P</italic><sub>r</sub>, and BDS levels, attributed highly dynamic polar nano-regions.
In this study, activated carbons (ACs) were produced from coal using potassium hydroxide as a chemical-activating agent. The preparation procedure composed of KOH impregnation followed by activation at 700°C–900°C under the nitrogen atmosphere for time duration 1 h. effects various temperatures and to ratios on porous structure products examined. resulted ACs also characterized techniques such Brunauer-Emmett-Teller (BET) analysis, Fourier-transform infrared spectroscopy (FTIR), scanning...
Composition of ceramics 0.92BaTiO3–0.08Bi(Mg0.5Ce0.5)O3 + xwt % MnO2 {designated as BTBMC-x wt Mn} (0.00 ≤ x 0.20) was fabricated via a solid-state sintering route for the investigation phase, microstructure, dielectric, electrical, and energy storage behaviors. X-ray diffraction results indicated single phase without an impurity phase. The additive led to decrease in average grain size BTBMC ≤0.2 μm (submicron), which decreased electrical conductivity from ∼10–6 s cm–1 ∼10–10 when value...
Abstract The purpose of this paper was to prepare purified Na- bentonite with improved properties for use in the pharmaceutical industry. Calcium from Shagia region Karak district, Pakistan, activated various proportions sodium carbonate (2, 3, 5 and 8 wt.%) by sedimentation remove impurities, especially quartz. X-ray diffraction (XRD), swelling volume confirmed conversion raw using 5% Na 2 CO 3 . (K5) obtained activation met chemical microbiological requirements set pharmacopeias regarding...
All the compositions in (1−x)Mg0.95Ni0.05Ti0.98Zr0.02O3–xCa0.6La0.8/3TiO3 (0 ≤ x 0.2) series were fabricated using solid state sintering route. Mg0.95Ni0.05Ti0.98Zr0.02O3 possessed excellent microwave dielectric properties with ε r ≈ 17.1, Q u f0 195855 GHz, and τ f -46 ppm/°C. was tuned through zero by mixing Ca0.6La0.8/3TiO3.
