Mixed fuel synthesis of Y2O3 nanopowder and their applications as dispersoid in ODS steel

Effect of lithium borate coating on the electrochemical properties of LiCoO2 electrode for lithium-ion batteries

“…For the production of cathode materials, different modifications of solid-phase and hydrothermal methods are usually employed [12]. In laboratory studies for the obtaining of the cathode materials, in particular, lithium cobaltite, combustion reactions [13][14][15][16][17][18] are more often used [19][20][21][22][23][24]. The attraction of solution combustion synthesis (SCS) reactions for industrial application is determined by the following characteristics: 1. cathode material can be produced almost without sewage; 2. energy consumption for the decomposition of precursors is reduced compared to conventional technologies, since the method employs internal exothermal processes requiring only relatively moderate energy consumption for evaporation of reaction solutions and preliminary heating of xerogel before the beginning of redox reaction; 3. dispersion and chemical activity of produced precursor may reduce the time of high-temperature annealing to attain the monophasic; 4. although the initial solutions contain nitrates, combustion proceeds with almost complete transformation of nitrogen dioxides into molecular nitrogen; 5. this method allows to control the dispersion of the material while reducing the costs for milling and lessening the risk of pollution of the material during milling.…”

Evaluation of Structural and Optical Properties of Nanocrystalline Cubic Y2O3 Phase Materials via Combustion Method Using Different Fuels

“…S1 (available online at stacks.iop.org/JSS/ 11/063001/mmedia)). The properties of the Y 2 O 3 phase materials have been extensively investigated mostly on structural, 18,22,34,40,41,43 morphology, 13,14,24,28,30,38,42,48 thermal stability, 13,25,45 and optical. 15,24,48 The optical properties are well supported by spectroscopic techniques, such as UV-vis-NIR, 15,24,25,29,36,39,48 FTIR, 14,15,24,27,32,41,45 and Raman.…”

“…Combustion synthesis is a redox reaction between nitrate and fuel, which can produce a variety of oxidebased nano-structured materials. 10 From the collected articles, we explored that the Y 2 O 3 phase nanomaterials have been obtained via combustion method using urea, 13,48 glycine, 13,22,28,34,48 ethanol, 14 citric acid, 13,28,30,34 EDTA, NA 2 -EDTA, 24 ethylene glycol 28 as fuels. Significant changes have been seen in the phase formation and properties of the final products by these above fuels.…”

“…Significant changes have been seen in the phase formation and properties of the final products by these above fuels. Jayasankar et al 28 used citric acid, ethylene glycol, and glycine as single and mixed fuels that showed notable effects on thermal and microstructural features.…”

“…Such a type of above comparative fuels has not been used to synthesis Y 2 O 3 nanomaterials as compared to the existing reports. 13,14,22,24,28,30,34,48 Different characterizations namely, X-ray diffraction (XRD), thermal gravimetric (TG) and differential thermal analyses (DTA), ultraviolet-visible-near-infrared (UV-vis-NIR), Fourier-transform infrared (FT-IR), Raman spectroscopy, and field emission scanning electron microscope (FESEM), and energy-dispersive X-ray analysis (EDX) techniques have tested the crystallinity and properties of different types of samples studied here. All the results are compiled and analyzed based on these techniques and reported here as a comparative novel study.…”
