The characterization of the gel structure by means of small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) is described by taking the examples of monovalent and bivalent cation κ-carrageenates in aqueous solution, polyvinyl alcohol)-borate gels and the inorganic/organic hybrid gels from tetraethoxysilane and poly(oxytetra-methylene). The SAXS and SANS results were analysed and discussed in terms of the classic gelation thoery as well as the scaling concepts.
