Lecture 19: Sol- Gel Science

Applications

• It can be used in ceramics manufacturing processes, as an investment casting material, or as a means of producing very thin films of metal oxides for various purposes.

• Sol-gel derived materials have diverse applications in optics, electronics, energy, space, (bio)sensors, medicine (e.g. controlled drug release) and separation (e.g. chromatography) technology. One of the more important applications of sol-gel processing is to carry out zeolites synthesis.

• Other elements (metals, metal oxides) can be easily incorporated into the final product and the silicalite sol formed by this method is very stable.

• Other products fabricated with this process include various ceramic membranes for microfiltration, ultrafiltration, nanofiltration , preevaporation and reverse osmosis.
