sol-gel processing
solgel processing
The process of the settling of (nm sized) particles from a colloidal suspension onto a pre-existing surface, resulting in ceramic materials. The desired solid particles (e.g. metal alkoxides) are suspended in a liquid, forming the 'sol', which is deposited on a substrate by spinning, dipping or coating, or transferred to a mould. The particles in the sol are polymerised by partial evaporation of the solvent, or addition of an initiator, forming the 'gel', which is then heated at high temperature to give the final solid product.
