Influence of surfactants on co-precipitation synthesis of Bi–YIG particles

Molten-salt synthesis and characterization of Bi-substituted yttrium garnet nanoparticles

“…2, the characteristic peak of Bi-YIG phase can be observed after the OM being calcined at 600 • C for 2 h in NaCl-KCl eutectic mixture. Comparing with our early study [23], The XRD patterns of MSS-particles and CHP-particles are almost the same, but the Bi-YIG phase formation temperature (600 • C) of MSS-particles is much lower than that of CHP-particles (650 • C), this could be attributed to the enhanced diffusion in the molten chlorides liquid phase compared to that in the solid state.…”

“…Bi-YIG (Bi1.8Y1.2Fe5O12) precursors were prepared by co-precipitation method according to literatures [23,24]. In a typical procedure, ammonia aqueous solution (pH 11) was ground at a flask for 5 min, and then a mixture solution of bismuth nitrate, iron nitrate and yttrium nitrate in an adequate proportion was added dropwise under vigorous stirring at room temperature, at the same time, some more ammonia aqueous solution was added to keep the pH constant during the coprecipitation.…”

The product was washed with deionized water and absolute alcohol, and dried in an oven at 100 • C for 3 h. To obtain the oxides mixture (OM) of Bi2O3, Y2O3 and Fe2O3 with a certain ratio, the above-prepared Bi-YIG precursors were heated in a muffle furnace at 510 • C for 1.5 h (the heating temperature we chose was according to the thermal analysis in our early study [23]). …”

Determination Reflection and Transmission Coefficients of Lanthanum Iron Garnet Filled PVDF-Polymer Nanocomposite Using Finite Element Method Modeling at Microwave Frequencies

“…Determination of reflection and transmission coefficients of garnet ferrites loaded polymer nanocomposites have attracted the interest of many researchers and scientists due to their applications in microwave and electronic devices such as isolators, filters and circulators [1][2][3].…”

Microwave-assisted synthesis and characterization of Bi-substituted yttrium garnet nanoparticles

“…A variety of methods have been used to prepare YIG nanoparticles, including ball milling [7,8], coprecipitation [9][10][11][12], microemulsion [13], hydrolysis of metal alkoxides and amorphous citrate gel [14][15][16]. Each method has its own distinctive advantages.…”
