A study of the sol-gel process of sols of hydrated oxides by SAXS using synchrotron radiation
No full textSols of some electrochemically produced hydrated oxides (original sols) and their mixtures (binary sols) are studied by SAXS using synchrotron radiation (SR). The presence of 1–2 nm scattering entities (primary particles) is a characteristic property of the investigated sols. During gelation and concentration of the original sols the interparticle distance varies in different ways. The binary sols gelate without concentration of the system. Particles with different sizes are observed in the binary sols. It is possible to separate two sections (time intervals) on the kinetic curves of the structural parameters concerning the changes in the binary sols
