“…In order to prepare highly homogeneous ultrafine particles of barium hexaferrite, several non-conventional low-temperature chemical methods were developed for the formation of ultrafine BaFe 12 O 19 particles in last few years. These methods employed co-precipitation [11][12][13][14], hydrothermal [15][16][17], solgel [18][19][20][21], microemulsion [22], citrate precursor [23], salt melt method [24], glass crystallization [25,26], sonochemical [27], combustion [28] and mechano-chemical activation [29,30]. The chemical co-precipitation method is a lowcost technique compared to the other mentioned methods, suitable for mass production.…”

Sr-M-type hexagonal ferrites have been prepared via a sol-gel route, and the effects of addition of different molecular weight polyethylene glycol (PEG) into the sol solutions on the static magnetic properties and particle morphology have been studied. Crystalline phases of the samples were determined by XRD analysis. FT-IR and TG analyses were used to prove the presence of PEG on SrFe 12 O 19 . The results showed that adding PEG with different molecular weight into the sol solutions affected the formation mechanism of SrFe 12 O 19 . Sr-M precursors prepared by various PEG types show different magnetic behaviors after precalcination at 150 • C. This discrepancy is explained by the formation of a different phase during the synthesis of SrM particles.

“…Magnetic properties of Ba or Sr ferrite powders strongly depend on the microstructure [3]. In order to get pure crystalline domain particles, various synthesis techniques have been developed, such as sol-gel technique [4], micro emulsion [5], hydrothermal reaction [6] and salt-melt technique [7]. Particularly, sol-gel technique is a novel method which can be used to prepare high-powered hexaferrites.…”

Magnetic materials are important electronic materials that have a wide range of industrial and commercial applications. Barium strontium hexaferrite (Ba 0.5 Sr 0.5 Fe 12 O 19 -BSF) were prepared by a sol-gel method using D-Fructose as fuel and the heat treatment was carried out in a microwave furnace. The effects of the sintering temperature on the morphology, crystalline structure and magnetic properties are studied. Sintering temperature affected the grains in compact samples. The sintered product possessed dense microstructure with clear micro grains and is in consistence with the XRD analysis based on the peak intensity of the (107) plane. Magnetic measurement shows that the barium strontium hexaferrite sample sintered at 1,150°C has the coercive field of 1,998 Gauss, remnant magnetization of 38.87 emu/g and the saturation magnetization of 53.44 emu/g.

“…Also along with further research and increasing demands for microwave communication, microwave dark room, the anti-electromagnetic wave radiation, the barium ferrite has been caused great attention [1][2][3][4]. In order to get high-powered barium ferrite, people are trying their best to obtain pure crystalline mono-domain particles of BaFe 12 O 19 , different synthesis techniques have been developed, such as sol-gel technique [5], microemulsion [6], hydrothermal reaction [7], glass crystallization [8], salt-melt technique [9], etc. Particularly, sol-gel technique is a new method which can be used to prepare for high-powered nanocrystalline BaFe 12 O 19 .…”
