Synthesis and Characterization of Lithium-Doped Tin Dioxide Nanocrystalline Powders by Emulsion Combustion Method

摘要

Li doped SnO₂ nanoparticles were synthesized using an emulsion precursor derived from a mixed-metal and oleic acid solution. The precursors and derived oxide powders were characterized by differential thermal analysis, thermogravimetric analysis, X-ray diffraction (XRD), transmission electron microscopy (TEM), and Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES). The XRD studies reveal that the material is assigned to be SnO₂ tetragonal Cassiterite phase. The average particle size as determined from TEM varies in the range 12-181Â nm. The amount of Li content in the sample determined by ICP-AES was found to 1.615Â wt%.View full textDownload full textKeywordsCeramics, Crystal structure, Differential thermal analysis, Emulsion combustion synthesis, Inductively coupled plasma atomic emission spectrometer, Lithium, Microstructure, Nanoparticle, Oleic acid, Tin oxide, Transmission electron microscopy, Thermogravimetry analysis, X-ray diffractionRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10426910903447246
