Combustion synthesis of alkaline-earth substituted lanthanum manganites; LaMnO3, La0.6Ca0.4MnO3 and La0.6Sr0.4MnO3

Spontaneous formation of crystalline lithium molybdate from solid reagents at room temperature

“…These self-heating reactions can be driven by either metathesis [22][23][24] or combustion. 25,26 Once initiated these reactions proceed rapidly and can be complete within seconds. 27 The properties of molybdates are of interest for a number of possible applications including corrosion inhibitors 28 and hosts matrices for lasers.…”

Modified self-propagating high-temperature synthesis of nanosized La0.7Ca0.3MnO3

“…For example, NaClO 4 was used as internal oxidizer of Mn metal during synthesis of polycrystalline mixed manganites [22], while the introduction of carbon as an internal fuel was reported in [23] for synthesis of submicron perovskite powders. Recently, Hwang et al [24] have used aqueous solution of metal nitrates and organic fuel in the first phase of synthesis (as a part of typical SC procedure), but skipped self-ignition stage in liquid phase and conducted the combustion of the dried residue instead, to obtain nanoscale Ni-Zn ferrite powder.…”

Synthesis of novel perovskite crystal structure phase of strontium doped rare earth manganites using sol gel method

“…[14,15] The large S M was determined around 300K for manganese perovskites with large magnetic entropy changes induced by low magnetic field change [16], which is beneficial for the household application of active magnetic refrigerant materials. Crystal structure of rare earth manganite is not only a cubic perovskites structure but also is orthorhombic [17,18], rhombohedral [19], hexagonal [20] or monoclinic [21] depends on the synthesis procedure and heat treatment. The crystal structure P6 3 cm (JT ions free) phases.…”
