Anisotropy of crystallite growth during sintering of SnO2 xerogels
(1996-12-01)
The crytallite and pore-size evolution during isothermal sintering (400 ≤ T ≤ 700°C) of SnO2 xerogels was studied by X-ray line broadening and nitrogen adsorption-desorption isotherms. The experimental results show a strong ...
Microwave-assisted hydrothermal synthesis of structurally and morphologically controlled sodium niobates by using niobic acid as a precursor
(Wiley-v C H Verlag Gmbh, 2008-03-01)
There are many advantages to using a microwave as a source of heat in hydrothermal reactions. Because it is a quick and homogeneous way to crystallize ceramic powders, it was used in this work for the production of ...
Controlling the growth of zirconia needles precursor from a liquid crystal template
(Elsevier B.V., 2010-01-05)
This work reports the directional growth of macroscopic ceramic needles by combining a thermo-responsive Sulfated hydroxy zirconyl (SHZ) hydrosol with a swollen hexagonal liquid crystal (SHLC). The effect of the molar ratio ...
Growth kinetics of vanadium pentoxide nanostructures under hydrothermal conditions
(ElsevierAmsterdam, 2010-11)
The work reported here involved a study of the growth kinetics of V2O5nH2O nanostructures under hydrothermal conditions. The coarsening process of V2O5nH2O nanoribbons was followed by subjecting the as-prepared suspensions ...
Understanding the Crystallization Mechanism of a Wollastonite Base Glass Using Isoconversional, IKP Methods and Master Plots
(Wiley-Blackwell, 2012-11-01)
The complex development of crystals found in the crystallization of SiO2-Al2O3-CaO-Na2O glass has been explained using Differential Thermal Analysis. The crystal growth process has been studied using isoconversional, ...
Crystallization of amorphous GaAs films prepared onto different substrates
(2002-04-01)
This work reports changes in structural properties produced by thermal annealing of flash evaporated amorphous GaAs films using the micro-Raman scattering and the X-ray diffraction (XRD) techniques. Films of about 1 μm ...
beta-ZnMoO4 microcrystals synthesized by the surfactant-assisted hydrothermal method: Growth process and photoluminescence properties
(ELSEVIER SCIENCE BVAMSTERDAM, 2012-02-20)
In this communication, we investigate the effect of different surfactants: cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS) and polyvinylpyrrolidone (PVP-K40) on the growth process of zinc molybdate ...
Templated CaCO3 Crystallization by Submicrometer and Nanosized Fibers
(2016)
Electrospun submicrometer-sized poly(e-caprolactone) (PCL) meshes and nanosized multiwalled carbon nanotubes (MWCNTs) were used as a template for preparing porous and interconnected inorganic organic hybrid materials ...
Crystallization kinetics of glass prepared with foundry slag
(2021-07-01)
Iron foundry slag and hydrated lime were used in glass preparation by the melt-quenching method. The glass obtained was heat-treated using the thermal analysis technique. A crystallization kinetics study was carried out ...
New methodology based on static light scattering measurements for evaluation of inhibitors for in bulk CaCO3 crystallization
