Variations in an oleic acid and metal nitrate emulsion under calcination on the structural and morphology of LaAlO3 nanopowders

The Influence of Oleic Acid to Metal Nitrate Ratio on the Particle Size and Magnetic Properties of Lanthanum Ferrite Nanoparticles by Emulsion Method

“…The small reaction field and short reaction period lead to the formation of nanosize ceramic particles [16]. This technology, also known as calcination control of chemical additives (CCCA), has been used in previous studies for the preparation of LaAlO 3 [17,18], BaTiO 3 [19], Al 2 O 3 [20][21][22], ZrO 2 [23], -Al 2 O 3 -t-ZrO 2 [24], LiCoO 2 [25], Yttria stabilized zirconia [26], ZrO 2 -CeO 2 [27], ZnO [28], Fe 2 O 3 [28], CeO 2 [28], MgO [28], and ZnO-SiO 2 [29] fine powders. Hollow spheres of Al 2 O 3 TiO 2 ZrO 2 Y 2 O 3 , and solid particles of ZrO 2 -CeO 2 , ZnO, Fe 2 O 3 CeO 2 , MgO, and BaTiO 3 can be prepared by this process.…”

“…Recently, Lee et al [22] prepared nano -Al 2 O 3 with a favorable range of particle size near 30 nm by calcining an emulsion precursor derived from aluminium nitrate and oleic acid. Chandradass et al [17,18,22] prepared LaAlO 3 and -Al 2 O 3 -t-ZrO 2 nanopowders by calcining an emulsion precursor. The particle size of nanopowders prepared by emulsion method is comparatively smaller than the other combustion methods reported in the literature [30][31][32].…”
