New sol–gel route for SiO2/ZrO2 film preparation

Improving the Corrosion Performance of Organically Coated Steel Using a Sol–Gel Overcoat

“…The most extensively studied alkoxide precursors are silane-based as they are low cost, widely available and are of lower reactivity compared to other alkoxide precursors based on alumina, titania and zirconia [15][16][17]. Sol-gel coatings are formed in four stages: hydrolysis, condensation, chain growth and agglomeration [18]. Once the sol has been prepared, hydrolysis and condensation reactions take place, which produce alcohol and water, as shown in Reactions (1)(2)(3).…”

Stabilization of tetragonal phase of nanostructured Fex/ZrO2 system (0 ≤ x ≤ 25) prepared by modified sol-gel method

“…There are several methods for the synthesis of pure and doped zirconia nanoparticles at different phases, including hydro-thermal [19], mechano-chemical [20], Thermolysis [21], spray pyrolysis [22], sonochemical [23] and emulsion precipitation [24]; however, these synthesis techniques have some drawbacks that would complicate their ability to be applicable on different scales. On the other hand, the Sol-gel synthesis technique can provide a green synthesis route, simple and significant yield, and most importantly fast route to synthesize zirconia nanoparticles [25][26][27][28].…”

The variations of hydrophilic self-cleaning properties and refractive index dependence in the ZrO2 thin films by Gamma Irradiation

“…[3] . The sol-gel process also allows the deposition of films and coatings with variable thickness from nm to micrometer, in an easy and fast way, by the use of either dip-, spin-or spray-coating procedures [6] . The ZrO 2 thin film can be produced with refractive indices n ranging from 1.35 to 2.50 and film thicknesses d from 150 to 1500 nm.…”
