Structural characterization of Ba1.„Sr„TiO3 (BST) nanopowders prepared by stearic acid gel method
Stoichiometric tetragonal Bal-xSrxTiO3 (x = 0.23) nanopowders were prepared by stearic acid gel(SAG) method using barium stearate, strontium stearate, tetrabutyl titanate as Ba, Sr, Ti sourcesand stearic acid as complexing reagent. Thermal analysis including differential thermogravimetric(DTG) and TG, Fourier transform infrared spectrometry (FTIR), X-ray diffraction (XRD) andtransmission electr...
متن کاملElectrical and magnetic properties of barium hexaferrite nanoparticles prepared by citrate precursor method
Ferromagnetic nanomaterials are of particular interest, because at nanoscale a crystallite can exhibit a single magnetic domain. These nanomaterials therefore exhibit different magnetic properties as compared to bulk. Recently, barium ferrite has gained importance due to its potential use in magnetic recording and in microwave devices. Barium ferrite nanoparticles are prepared by the citrate pr...
متن کاملSTUDY OF THE OPTIMUM CALCINATION TEMPERATURE FOR THE SYNTHESIS OF STRONTIUM HEXAFERRITE MAGNETIC CERAMIC NANOPOWDER BY A SOL-GEL AUTO-COMBUSTION METHOD IN THE PRESENCE OF CATIONIC SURFACTANT
In this research the sol-gel auto-combustion method was used to prepare strontium hexaferrite nanopowder. A solution of distilled water, ferric and strontium nitrates, citric acid, trimethylamine, and n-decyltrimethylammonium bromide cationic surfactant, was heated to form a viscous gel. The gel was heated and then ignited automatically. As-burnt powder was calcined at temperatures from 700 to ...
متن کاملSurfactant-assisted synthesis of Barium hexaferrite nanoparticles by hydrothermal method
In the present work, the synthesis of Barium hexaferrite (BaFe12O19) nanoparticles in thepresence of a large excess amount of OH− anions by the hydrothermal method in the presence and absence of surfactants such as Sodium dodecyl benzene sulfonate and Triton X-114 was reported. The optimized temperature in the absence of surfactant was determined (200 °C) and then Barium hexaferrite nanoparticl...
متن کاملDesign of Microstrip patch antenna with Hexaferrite Cavity in X-band
In this paper, a microstrip patch mounted on high impedance substrate with hexaferrite cavity is proposed. The proposed antenna design is simulated on electromagnetic (EM) simulation software using FR-4 substrate with dielectric constant of 4.4 and thickness of 1.60mm. The proposed antenna has a compact structure with a total size of 50.8x50.8mm. A microstrip fed low profile broadband dielectri...
