WebApr 8, 2024 · In this work, to prepare the PbZr 0.52 Ti 0.48 O 3 (PZT)/PbZrO 3 (PZ) multilayer films, PZ films and PZT films were spin-coated on LaNiO 3 /SiO 2 /Si substrates in sequence by the sol-gel method, and the PZ films were prepared using PZ precursor solution with different concentrations. After each spin-coating, PZ layer and PZT layer were annealed … WebApr 10, 2024 · 2.1 Preparation and characterization of Nb 2 O 5 thin films. The sol–gel spin coating technique was used to develop single-layer and multi-layer niobium pentoxide (Nb 2 O 5) thin films on silicon (Si) substrates.To get the viscous solution, 1.6 g NbCl 5 was dissolved in 33.2 ml ethanol and 0.68 ml distilled water. The mixture was stirred at room … 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 alkyl group R = C2H5. Alkoxides are ideal chemical precursors for sol–gel synthesis … 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 solution) evolves gradually towards the formation of a gel-like network containing both a liquid phase and a solid phase. … See more Sonication is an efficient tool for the synthesis of polymers.
