Item type:Publication, Fabrication of new (Ba0.97Ca0.03)(Zr0.94Sn0.06)O3 ceramics by the combustion technique(2016-01-26); Bongkarn, TheerachaiIn this study, new (Ba<inf>0.97</inf>Ca<inf>0.03</inf>)(Zr<inf>0.94</inf>Sn<inf>0.06</inf>)O<inf>3</inf> BCZS ceramics were synthesized by the combustion technique using glycine as fuel. The powders and ceramics were calcined from 1,000 to 1,200 °C for 2 h and sintered from 1,500 to 1,675 °C for 2 h. A pure perovskite phase was found in the powder calcined at higher than 1,150 °C and the purity phase of the ceramics was detected in all samples. The average particle size and grain size increased approximately from 73 to 103 nm and from 0.51-1.61μm when firing temperatures increased. The calcined powders exhibited tight agglomerates at low calcination temperatures and they changed to loosely bound agglomerates at higher calcination temperatures. The densest ceramics were discovered in the samples sintered at 1,650 °C. The dielectric constant (ε<inf>r</inf>) and loss factor (tan δ) values measured at 100 kHz of this sample were found to be 44 and 0.01, respectively at room temperature. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Direct synthesis and growth mechanism of metal molybdate (AMoO4; A = Ca and Ba) fine particles via the mechanochemical method(2017-08-01); Metal molybdate (AMoO<inf>4</inf>; Ca and Ba) fine particles were synthesized successfully in a simple way using the mechanochemical method under ambient conditions, without surfactants or any capping agents. The effect of milling time on phase formation and morphology was investigated. The functional group and phase formation analyses were carried out using Fourier transform infrared (FT-IR), Raman spectroscopy and X-ray diffraction (XRD) methods. XRD revealed that all samples were of a pure tetragonal scheelite structure. FT-IR and Raman analysis exhibited a Mo-O stretching peak of molecular [MoO<inf>4</inf>]<sup>2-</sup>, which related to the scheelite structure. Difference in growth mechanism and morphology was observed significantly in CaMoO<inf>4</inf> and BaMoO<inf>4</inf> particles. The primary CaMoO<inf>4</inf> nanocrystalline was formed in its initial state at 80–100 nm, and tended to aggregate into a peach-like shaped morphology with increasing milling time, while a space shuttle-like morphology formed directly via an oriented attachment mechanism for the BaMoO<inf>4</inf> particle. A possible mechanism for the formation of metal molybdate, with a different milling time, was discussed in detail. It is interesting that this work was able to present a simple way of synthesizing complex oxide materials on a large scale. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, ELECTRIC AND MAGNETIC PROPERTIES OF Ba0.97Ca0.03Ti0.94Sn0.06O3-Mn0.85Ni0.15Zn0.15Fe2O4 MULTIFERROIC CERAMIC COMPOSITES FABRICATED VIA THE SOLID-STATE COMBUSTION TECHNIQUE(2025-01-01); Pinitsoontorn, SupreeMultiferroic composites with the general formula (1-x)(Ba0.97Ca0.03Ti0.94Sn0.06O3)-x(Mn0.85Ni0.15Zn0.15Fe2O4) (BCTS/MNZF) (x = 0.1, 0.2, 0.3, 0.4, and 0.5) were prepared using the solid-state combustion method. The structure, morphology, dielectric, ferroelectric, magnetic, and magnetoelectric properties were analyzed. The samples were sintered at 1,300ºC for 2 h. The X-ray Diffraction (XRD) patterns revealed tetragonal perovskite, orthorhombic perovskite, and cubic spinel structures corresponding to the BCTS and MNZF phases. Secondary phases (Mn2O3 and SnO) appeared in the sintered samples with x>0.2. Increasing MNZF content enhanced ferrite grain growth in the composites. The dielectric constant showed an overall decreasing trend with increasing MNZF content, with a smaller effect at lower frequencies. At lower frequencies, the dielectric constant declined with increasing frequency before stabilizing around 10 kHz. As ferrite content increased, the density, dielectric constant, and magnetoelectric coefficient (αME) decreased from 5.66 to 5.12 g/cm³, 1388 to 862, and 7.24 to 4.05 mV/cm·Oe, respectively. While the saturation magnetization (Ms) rose substantially from 0.75 to 13.14 emu/g. These findings offer valuable insights into enhancing lead-free multiferroic composite ceramics for targeted applications in magnetoelectric devices.
