“…Here we show that monophasic rare-earth cobaltite materials can be obtained by MWassisted synthesis within 30 minutes with massive time and energy savings. LaCoO3 has been synthesized previously by innovative and novel chemical synthesis methods [28][29][30], including MW-assisted processes [11,31,32], but the rest of the series (RE = Pr -Dy) has not been prepared before using MW heat sources to the best of our knowledge.…”

AbstractThe series of perovskite rare-earth (RE) doped cobaltites (RE)CoO3 (RE = La -Dy) was prepared by microwave-assisted synthesis. The crystal structure undergoes a change of symmetry depending on the size of the RE cation. LaCoO3 is rhombohedral, S.G. , while for the rest of the RE series (Pr -Dy) the symmetry is orthorhombic, S.G. Pnma (No. 62). The crystal structure obtained by X-Ray diffraction was confirmed by high resolution transmission electron microscopy, which yielded a good match between experimental and simulated images. It is further shown that the well-known magnetism in LaCoO3, which involves a thermally induced Co 3+ (d 6 ) low spin to intermediate or high spin state transition, is strongly modified by RE-doping and a rich variety of magnetic order has been detected across the series.

“…Various low temperature chemical routes such as coprecipitation [23], decomposition of heteronuclear complex [24][25][26][27], mechanochemical synthesis [19], combustion method [28], sol-gel [29] and pechini-type polymerizable complex [30][31][32][33] have been reported for obtaining pure phase LaCoO 3 nanopowder with high surface area and well-defined chemical compositions. However, most of these processes are either complex or expensive and limit their large-scale production.…”

Synthetic inorganic pigments are most widely used in ceramic applications due to their excellent chemical and thermal stability and their lower toxicity to both human and environment as well. In the present work, black ceramic pigment CoFe 2 O 4 has been synthesized by the complex polymerization method (CPM) with good chemical homogeneity. In order to study the influence of variables on the process of obtaining pigment through CPM, 2 (52) fractional factorial design with resolution III was used. The variables studied in the mathematical modeling were: citric acid/metal concentration, pre-calcination time, calcination temperature, calcination time, and calcination rate. Powder pigments were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-visible (UV-Vis) spectroscopy. Based on the results, the formation of cobalt ferrite phase (CoFe 2 O 4 ) with spinel structure was verified. The color of pigments obtained showed dark shades, from black to gray. The model adjusted to the conditions proposed in this study due to the determination coefficient of 99.9% and variance (R²) showed that all factors are significant at the confidence level of 95%.
