Co-precipitation method for the preparation of fine ferroelectric BaBi2Nb2O9

Effect of sintering temperature on microstructure and electrical properties of Sr1−x(Na0.5Bi0.5) x Bi2Nb2O9 solid solutions

“…There are numerous reports on the synthesis of bismuth niobate and its solid solutions by processes such as solid-state reaction [6][7][8], aqueous solution method [9,10], organic precursor decomposition [11,12], co-precipitation [13][14][15], sol-gel [16,17], and combustion synthesis [18] which often results in high agglomeration of powders. For these several chemical synthesis routes, a high sintering temperature is usually necessary for the densification of ceramics [19].…”

Low-temperature synthesis of La0.6Sr0.4Co0.2Fe0.8O3−δ perovskite powder via asymmetric sol–gel process and catalytic auto-combustion

“…Consequently, both the electrical and mechanical properties of the final sintered ceramic products by the conventional standard method are not adequate for many advanced applications. In order to obtain homogeneous fine powders, other different methods via various wet-chemistry routes such as freeze-drying, co-precipitation and combustion of metal-organic precursors, have been proposed [13][14][15][16][17][18][19][20][21][22]. Among these techniques, the combustion method based on water-soluble chelated complexes as precursors to obtain the homogeneity of the metal ion distribution on the atomic level, is currently attracting considerable attention.…”

Effects of preparation methods on the oxygen nonstoichiometry, B-site cation valences and catalytic efficiency of perovskite La0.6Sr0.4Co0.2Fe0.8O3−δ

“…La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3Àd is a typical example of these perovskite materials and has been widely studied for these application purposes. Applications of these MIEC composite oxides always start with the high-quality powder synthesis and several methods like solid state reaction, freeze-drying, sol-gel, hydrothermal, co-precipitation and combustion of metal-organic precursors have been employed [11][12][13][14][15][16][17][18][19][20]. Among these methods, sol-gel and low temperature combustion are often cited as novel synthesis techniques for advanced applications.…”
