THE EFFECT OF THE COLORING OXYHYDRATE GELS OF SOME RARE-EARTH ELEMENTS (Y,Gd,La)
Gel oxyhydrate systems of high-density metals (titanium, zirconium, rare earth metals and others) are living systems. Therefore, processes develop in polymer matrices that result in a certain directed morphogenesis of the matrices. The effects of cross-linking occur through the intermicellar molten phase by the link destruction of gel fragments (gel protonation), the transfer of light (monomolecular) fragments in solution and their subsequent diffusion to the active gel center of polymerization (the formation of an active system), and the secondary directed copolymerization with the matrix's gel. Owing to the thin texturing of the gels, several specimens of the oxyhydrates of yttrium and gadolinium are colored. For practically all colored oxyhydrates of yttrium and gadolinium the color changes from a yellow-green or yellow to red, blue, or blue-green. The dynamic simulation of supramolecular structures of oxyhydrate compounds demonstrated the possibility of the formation, in the gel phase, of oxyhydrate of yttrium, of two structures similar in energy (A and B)
