## Sol Gel Technique for nanomaterials

Why the name sol-gel and technique

The sol-gel technique for synthesis of nanomaterials  is a wet- chemical technique. It is also known as chemical solution deposition. Such techniques are used for the fabrication of materials starting from a chemical solution (sol, short for solution) which acts as the precursor for an integrated network (or gel) of either discrete particles or network polymers. Precursors in the form of acetates or carbonates or nitrates are taken and then dissolved in deionized water. This starting material is used to produce a colloidal suspension known as gel. After that a gelling agent for example, polyvinyl alcohol is added and this will produce a gel. Continue reading “Sol Gel Technique for nanomaterials”
