The purpose of this work was to production of ceramic thin films by using of Sol-Gel process. For this purpose deposition of SiO2 on substrates of soda-lime glasses has been carried out. Coating treatments on prepared specimen were conducted in a Sol solution by means of dipping at various times. After drying and performing appropriate heat treatment on each sample, the thickness of coated laye...

The nanostructured anatase TiO2 with high thermal stability was prepared by polymeric sol-gel method without any additives. The particle size distribution of polymeric titania sol was determined by dynamic light scattering (DLS). Then properties of obtained titania were investigated by TG-DTA, XRD, FESEM and TEM. Also, the decolorization capability of resultant anatase was evaluated using methy...

A comparing study on formation and microstructure features of aluminum titanate is investigated through both solid-state and sol-gel processes. Aluminum titanate formed by firing at 1350ºC and 1450ºC for 4h in solid-state process. In the sol-gel process formation of submicron sized particles is followed by addition of sucrose into the transparent sol. XRD analysis was confirmed the formation of...

the aim of this study is to evaluate the influence of ph on the synthesis of nanocrystallines cobalt ferrite by combination of sol- gel auto combustion and ultrasonic irradiation methods. two different fuels, urea and thiourea, along with metal nitrates (oxidant) were used to prepare cofe2o4 powders. the morphology of the resulting powders was investigated. the powders were characterized by x-r...

Abstract: Lead-containing glass borosilicate was synthesized by Sol-gel technique using metalalkoxids such as tetraethyleorthosilicate (TEOS), Al-sec-butoxide and trimethyl borate. The sol containing TEOS converts to gel during drop wise addition of Al-alkoxide while inorganic lead salt was added in the last stage of gelation to prepare the alcogels. The specimens were dried at room tempera...

in this work, zno/sio2 nanoparticles were prepared using sol-gel method, and platinum particles were loaded on zno/sio2 nanoparticles by photoreductive method. samples were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform infrared spectroscopy (ft-ir). the xrd patterns showed that the zinc oxide samples have a wurtzite structure (hexagonal phase...

Zn1-xMgxO (x=0.00, 0.01, 0.02, 0.03, 0.04 and 0.05) solutions were prepared by sol-gel synthesis using acetate precursors which were dissolved into different solvents of ethanol, methaol, 2methoxyethanol and chelating agents of monoethanolamine, diethanolamine and triethanolamine . Syntehsized particles were then annealed at various temperatures and times and were observed for effect of doping ...

Nanocrystalline SnO2 thin films were successfully prepared using sol-gel dip coating technique. The starting precursor was used as tin chloride dihydrate (SnCl2.2H2O), ethanol and glycerin. As the prepared films were fired at 500 o C. These films were characterized using XRD, FESEM and TEM to known crystal structure, surface morphology and microstructure property. Elemental composition was stud...

The optical and structural properties of sol–gel prepared polycrystalline films of Cerium doped Lutetium and Yttrium oxyorthosilicates (Ce:LYSO) are investigated by means of optical spectroscopy, XRD diffraction and Raman spectroscopy. The sol–gel samples are compared to commercially available Ce-doped LYSO single crystals, and a detailed study of the emission properties from the different ceri...
