The sol–gel technique is defined as a colloid, that is, a dispersion of solid particles with diameters ranging from 1 to 100nm in a liquid, in which, after some process, the particles become interconnected, forming a rigid network with pores of submicrometer dimensions or polymeric chains (...

X-ray diffraction/ time-temperature-transformation diagramSol-Gel prepared PZT films of composition Pb1.05 (Zr0.53Ti0.47)O3 were isothermally annealed at different temperatures between 400°C and 700°C for various times and the phases formed were determined by X-ray diffraction. The sequence of ...
which depends on the measurement technique employed2. Similarly, it is not feasible to determine MGC for physical gels as a critical phase transition concentration because of the difficulty in observing precisely the point of disappearance of fluidity and the point of the appearance of a gel state...
Glass-ceramic powders with a composition of Li2O · Al2O3 · 4SiO2 (LAS) have been synthesized by the sol-gel technique using LiOCH3, Al(OC2H5)3, Si(OC2H5)4, Ti(OC2H5)4, and Zr(OC2H5)4 as starting materials and the phase transformation b... MH Lin,MC Wang - 《Journal of Mat...
Silica-based bioactive glasses (BGs) were first synthesized via a sol–gel technique by Li et al. [82] at lower processing temperatures compared to the melt-derived glasses. Pereira et al. [83], [84] extensively researched sol–gel glasses based on the SiO2–CaO–P2O5 system for biomedical...

The sol-gel technique is used to elaborate bulk glasses and thin films. Thin-film fabrication is of great importance, as most integrated optics devices are based on planar or channel waveguides. To obtain films by the sol-gel process, the sol is deposited on a substrate, which can be made...
Sol-gel particle sizes were determined using a Malvern Nano-ZS instrument, using the Dynamic light scattering (DLS) technique. The chemical bonding within the zirconium complexes was characterised by Fourier Transform Infrared Spectroscopy (FTIR, Perkin Elmer GX). The solution B was dried at 100°...
