A review of the literature shows that sol-gel process, also known as Stöber process, has proven to be a promising method for preparing monodispersed, nanosized Zinc Oxide (ZnO) thin films were prepared by sol gel method. Zinc acetate dehydrate, Methanol and Diethanolamine were used as a starting material, solvent CHAPTER 2 SOL-GEL PREPARATION AND … SOL-GEL PREPARATION AND CHARACTERIZATION TECHNIQUES 2.1 Deposition techniques The growth technique played a significant role in controlling the properties of ZnO films, because the same material deposited by two different techniques, usually had different physical properties. This is due to the fact that the electrical and optical properties of the Sol-Gel methods.pdf | Chemical Reactions | Catalysis The sol-gel method prevents the problems with co-precipitation, which may be inhomogeneous, be a gelation reaction. Enables mixing at an atomic level. Results in small particles, which are easily sinterable. The sol-gel method was developed in the 1960s mainly …

The evolution of ‘sol–gel’ chemistry as a technique for ...
A gel consists of a porous, three-dimensionally continuous solid network surrounding and supporting a continuous liquid phase (“wet gel”). In most sol–gel systems for the synthesis of oxide materials, gelation (i.e., formation of the gels) is due to the formation of covalent bonds between the sol parti-cles. Gel formation can be Thin Film Coating through Sol-Gel Technique Sol-gel technique has wide range of applications. One such application is the formation of thin film coatings through sol-gel which involves metal-organic or inorganic compounds as precursors 14. Mostly metal alkoxides are used as metal-organic precursors because they lead to a solid amorphous metal by (PDF) Thin Film Coating through Sol-Gel Technique The sol-gel technique is one of the easiest techniques for the preparation o f thin films, powder, xerogel, aerogels and glasses.
