“…Even the utilization of EDTA, known as a very strong complexing agent with four carboxylic acid groups, was unsuccessful (Liu et al 2010). It is interesting to note that the classical Pechini synthesis route (Pechini 1967) with citric acid and ethylene glycol has been reported both to give phase-pure (Popa et al 2007) materials and to give secondary phases (Ghosh et al 2005a). However, in the successful experiment, EG was used as a solvent, i.e.…”

The modified Pechini method has become one of the most popular synthesis methods for complex oxide materials due to its simplicity and versatility. The method can be applied to synthesize nano-crystalline powders, bulk materials as well as oxide thin films. Here, we present a comprehensive review of the method with focus on the chemistry through the three stages of the process; preparation of stable aqueous solution, poly-esterification to form a solid polymeric resin and finally decomposition/combustion of the resin to form an amorphous oxide followed by crystallization of the desired oxide phase. The review include

“…To date, synthesis of pure phase BiFeO 3 is still a challenging task. So far, bismuth ferrite particles were prepared mostly by the solid state and solution chemistry methods (i.e., precipitation/co-precipitation, solgel, hydrothermal and sonochemical) [13][14][15][16][17][18][19]. However, it resulted in the formation of coarser particles.…”

Abstract. Bismuth ferrite (BiFeO 3 ) is considered as one of the most promising materials in the field of multiferroics. In this work, a simple green route as well as synthetic routes has been used for the preparation of pure phase BiFeO 3 . An extract of Calotropis Gigantea flower was used as a reaction medium in green route. In each case so formed BiFeO 3 particles are of comparable quality. These particles are in the range of 50-60 nm and exhibit mixed morphology (viz., spherical and cubic) as confirmed by TEM analysis. These pure phase BiFeO 3 nanoparticles were first time surface modified effectively by mean of two silylating agent's viz., tetraethyl orthosilicate (TEOS) and (3-Aminopropyl)triethoxysilane (APTES). Modified and unmodified BiFeO 3 nanoparticles were efficiently introduced into polyvinylacetate (PVAc) matrix. It has been shown that nanocomposite prepared by modified BiFeO 3 comprise superior dispersion characteristics, improved ferroelectric properties and favorable magneto-dielectric properties along with excellent wettability in compare to nanocomposite prepared by unmodified BiFeO 3 . These preliminary results demonstrate possible applications of this type of nanocomposites particularly in the field of multiferroic coating and adhesives.

The milky juice obtained from Calotropis Gigantea is used for medicinal and insecticidal purposes [20]. The roots and leaves of Calotropis Gigantea are also used traditionally for treatment of abdominal tumors, boils, syphilis, leprosy, insect-bites and elephantiasis [21]. Extract of Calotropis Gigantean leaves also has significant antioxidant property. As reported in literature, there are numerous bio-organic compounds present in the plant systems such as flavonoids, terpenoids, proteins, reducing sugars and alkaloids [22,23]. These bio-organic compounds are supposed to be involved either as reducing agents or as stabilizing agent in the formation of nanoparticles. It is assumed that formation of nanoparticles occurs through the ionic or electrostatic interactions between the metal complexes and the functional groups on the biomass surfaces. But due to the bio-diversity of the plant biomasses, the exact mechanism by which bio-constituents of plants have contributed to the synthesis process is so far not completely understood. Moreover, though BiFeO 3 have many favorable properties, but still it is difficult to used directly. Being ceramic, as such BiFeO 3 is brittle in nature, very less shock resistive and has poor moldability [24]. To make it even more advantageous these disabilities ought to be rectified. The best way to do so is by making the composite of BiFeO 3 with a suitable polymer, since most of the polymers have better shock resistance, easy processability and being cheaper too. Also by judicious...

“…In some cases these methods seem successful in order to obtain BiFeO 3 nanoparticles [74][75][76][77][78], but divergences are also frequent. Actually it has been suggested that the BiFeO 3 obtained by these wet chemistry routes evidences a metastable behavior and under certain conditions -again contradictory [44,68]-it decomposes leading to secondary phase byproducts.…”
