Self-propagating high-temperature synthesis of LaMO3 perovskitetype oxide using heteronuclearcyano metal complex precursors Sánchez Rodríguez, Daniel Wada, Hiroki Yamaguchi, Syuhei Farjas Silva, Jordi Yahiro, Hidenori Compostos metàl·lics -- Síntesi Metallic composites -- Synthesis The decomposition of La[Fe(CN)6]·5H2O and La[Co(CN)6]·5H2O under different atmospheres has been analyzed by thermogravimetry (TG) and differential thermal analysis (DTA). In addition, the decomposition temperature at different sample locations was monitored for sample masses around 2 g of La[Fe(CN)6]·5H2O and La[Co(CN)6]·5H2O, when they were calcined for 1 h at temperatures ranging from 200 to 400 °C in a controlled gas-flow system. Results showed that, the large enough of the cyano complex precursors undergo combustion when they are decomposed under oxygen atmosphere. X-ray diffraction results revealed that perovskite-type oxides crystallize due to the overheating of the process. As a result, it has been possible to produce LaFeO3 and LaCoO3 perovskite-type oxide powders by SHS under oxygen atmosphere using La[Fe(CN)6]·5H2O and La[Co(CN)6]·5H2O as a precursor. The effect of the ignition temperature has been investigated. The specific surface area of the perovskite-type oxides produced via SHS using heteronuclearcyano metal complex as a precursor is significantly higher than that of other LaMO3 produced using the same technique but obtained from other type of precursors 2015-11-15 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion info:eu-repo/semantics/altIdentifier/doi/10.1016/j.jallcom.2015.07.246 info:eu-repo/semantics/altIdentifier/issn/0925-8388 Tots els drets reservats info:eu-repo/semantics/openAccess Elsevier © Journal of Alloys and Compounds, 2015, vol. 649, p. 1291-1299 Articles publicats (D-F) Sánchez-Rodríguez, Daniel Wada, Hiroki Yamaguchi, Syuhei Farjas Silva, Jordi Yahiro, Hidenori 2015 Self-propagating high-temperature synthesis of LaMO3 perovskitetype oxide using heteronuclearcyano metal complex precursors Journal of Alloys and Compounds 649 1291 1299
