In this paper, the synthesis of dicalcium silicate (C2S) via sol-gel (acid-catalyzed) process including aqueous route, non-aqueous and Pechini method is reported. The composition C2S (α, β, γ) polymorphs, by-products, amorphous content established by employing QXRD (quantitative X-ray diffraction) studies. attention has been focused to comprehend assay-amorphous relationships yield. intermediat...

Strontium titanate (STO) photocatalysts were prepared via a slightly modified Pechini sol–gel method. A unique rapid calcination technique with short exposure time was used to obtain crystalline products. The samples characterized by X-ray diffractometry, scanning electron microscopy, diffuse reflectance spectroscopy, infrared nitrogen adsorption–desorption measurements, and photoelectron spect...

The aim of this study represents the synthesis, characterization and photocatalytic activity determination of ZnO nanopowders synthesized using modified Pechini method. The obtained powders were characterized in what concerns their composition using X-ray diffraction, morphology using scanning electron microscopy and transmission electron microscopy and in what concerns the photocatalytic activ...

various morphologies of silica nanoparticles were synthesized by a microwave-assisted pechini method. silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in pechini procedure. then for preparation of polymer-matrix nanocomposites, sio2 nanoparticles were added to poly carbonate (pc) and poly...

Thin films of lithium niobate were deposited on (100) silicon by the polymeric precursor method (Pechini method). Annealing in static air was performed at 500 jC for 3 h. The films obtained were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Electrical characterization of the films pointed to ferroelectricity via hysteresis loop. The diele...

Thin films of lithium niobate were deposited on the Pt/Ti/SiO2 (111) substrates by spin coating from the polymeric precursor method (Pechini process). Annealing in static air and oxygen atmosphere was performed at 500 C for 3 h. The films obtained were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The dielectric constant and dissipation f...
