Question

sol gel method,,,,,,,,,,,,,,,,,,,,

Answer 1

The method is used for the fabrication of metal oxides, especially the oxides of silicon and titanium. The process involves conversion of monomers into a colloidal solution (sol) that acts as the precursor for an integrated network (or gel) of either discrete particles or network polymers.

Answer 2

Particles and polymers. The sol-gelprocess is a wet-chemical techniqueused 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.
