Nanomaterial by Sol-Gel Method: Synthesis and Application
In materials science, the sol–gel process is a method for producing solid materials from small molecules. The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). The process involves conversion of monomers into a colloidal solution (sol) that acts as the … See more In this chemical procedure, a "sol" (a colloidal solution) is formed that then gradually evolves towards the formation of a gel-like diphasic system containing both a liquid phase and solid phase whose morphologies range … See more The Stöber process is a well-studied example of polymerization of an alkoxide, specifically TEOS. The chemical formula for TEOS is given by Si(OC2H5)4, or Si(OR)4, where the See more For single cation systems like SiO2 and TiO2, hydrolysis and condensation processes naturally give rise to homogenous compositions. For systems involving multiple cations, such as strontium titanate, SrTiO3 and other perovskite systems, … See more The applications for sol gel-derived products are numerous. For example, scientists have used it to produce the world's lightest materials and also some of its See more The sol–gel process is a wet-chemical technique used for the fabrication of both glassy and ceramic materials. In this process, the sol (or … See more Sonication is an efficient tool for the synthesis of polymers. The cavitational shear forces, which stretch out and break the chain in a non … See more In the processing of fine ceramics, the irregular particle sizes and shapes in a typical powder often lead to polydisperse (non-uniform) packing morphologies that result in packing See more WebDec 14, 2004 · Sol-gel processing differs from other chemical processes because of its relatively low processing temperature.

WebErbium-substituted strontium stannates, with Er content 0{<=}x{<=}0.09, have been prepared by sol-gel method. The solubility limit of Er was found to be about 3%. The influence of temperature and the duration of the calcination, on the confirmation of single phase of Er doped SrSnO{sub 3} were investigated by using X-ray powder diffraction. The distribution … WebApr 7, 2024 · The gel electrolyte kept a transparent state, and the results of the inversion test confirmed gel formation, as can be evinced from Figure 1b. Figure 1c is a microscopic image of the gel after undergoing freeze-drying. This image demonstrates that the structure of the gel is that of a network of macropores of several micrometers in diameter.
