'''Sol gel''' is ana colloidal suspension of [[inorganic]], [[catalytic]] [[silicon oxide]] particles that is gelled to form a solid. The resulting porous gel can be chemically purified and consolidated at high temperatures into high purity [[silica]]. ItWith the sol gel process, silica can be usedmodified inwith a variety of [[ceramicdopant]]s to produce novel glass properties unattainable by other means. It can be used in ceramics manufacturing processes, as a mold to be washed away, or as a means of producing very thin films of metal [[oxide]]s for various purposes, including a form superior to [[teflon]].
