The formation mechanisms of the complex Ca-rich ferrite iron ore sinter bonding phases SFCA and SFCA-I, during heating a synthetic mixture in range 298–1623 K at pO2 = 0.21, 5 × 10–3 1 10–4 atm, were determined using situ X-ray diffraction. and, particular, SFCA-I are desirable sinter, improved understanding effect parameters such as on their may lead to ability maximise industrial sintering processes. both observed form 0.21 with preceding each case, but via distinctly different pO2. No was...
Raman spectroscopy is a powerful technique for the study of materials chemistry and nanostructure. This nondestructive highly sensitive to molecular crystal lattice vibrations, which allow comprehensive vibrational modes molecules incorporated in photovoltaic perovskite materials. In this study, we apply FAPbX3 (X = Cl, Br, I) FAxMA1–xPbI3 (FA stands formamidinium; MA methylammonium) metal halide single crystals discuss necessary conditions obtain reliable data. We establish correlation...

VO<sub>2</sub>(M) nanostructures with lower thermochromic phase transition temperature and narrower thermal hysteresis width were synthesized by a hydrothermal-calcination method, making them suitable candidates for smart windows.
Herein we outline a general one-pot method to produce large quantities of compositionally tunable, kesterite Cu2ZnSnS4 (CZTS) nanocrystals (NCs) through the decomposition in situ generated metal sulfide precursors. This uses air stable precursors and should be applicable synthesis range sulfides. We examine formation ligands, precursors, particles turn. Direct reaction CS2 with aliphatic primary amines thiols that already constitute mixture is used ligands situ. Through use 1H 13C nuclear...
Using the X-ray diffraction (XRD) patterns collected on products of laboratory furnace experiments performed a synthetic iron ore sinter mixture with composition 77.36 % Fe2O3. 14.08% CaO, 3.56% SiO2 and 5.00% Al2O3, it is demonstrated that previously reported Fe-rich SFCA phase has same crystal structure as triclinic SFCA-III. Therefore, four principal members silico-ferrite calcium aluminium (SFCA) family are SFCA, SFCA-I, SFCA-II, In addition, using XRD for strand pot-grate samples...

The relative effects of gibbsite, kaolinite and aluminous goethite as alumina sources on the thermal stability, concentrations formation mechanisms silico-ferrite calcium aluminium (SFCA SFCA-I) iron ore sinter bonding phases, was investigated using in situ X-ray diffraction. Iron containing gibbsite primary source is less likely to form high quality due lower reactivity leading low amounts SFCA-I SFCA phases being generated. Sintering this require higher fuel temperatures are required...

The effect of water on the surface structure 1-butyl-1-methylpyrrolidinium trifluoromethylsulfonylimide [C4mpyr][NTf2] ionic liquid was investigated using X-ray reflectometry. measured reflectivity data suggests a significant amount is adsorbed at surface, with first layer from gas (nitrogen)–liquid phase boundary mainly occupied by mixture cations and water. Beyond cation + layer, scattering length density increases towards bulk value, indicating decreasing cations, and/or an increasing...
We present a non-injection, one-pot synthesis of kesterite Cu2ZnSnS4 (CZTS) nanocrystals (NCs) that allows for multi-gram yields with precise control the NCs' metal composition. This is enabled through selective use binary sulfur precursor and ligand reaction mixture, which acts to decouple nucleation growth stages.

The physical properties of iron ore sinter are largely influenced by raw material properties, in particular the bulk composition and its associated mineralogy. levels Fe, SiO2, Al2O3, MgO other elements, together with nature minerals fine sintering conditions play a major role determining abundance type high-temperature bonding phases that form during sintering.
