摘要:
The synthesis of hydrolytically active heteroligand coordination compounds [M(C5H7O2)(3aEuro'x) (C5H11O (i) ) (x) ] (M = Fe3+ and Y3+) using iron and yttrium acetylacetonates has been studied. The gel formation kinetics in solutions of these compounds upon hydrolysis and polycondensation has also been studied. Thin films of a solution of these precursors have been applied to polished sapphire substrates by dip coating technology. The crystallization of nanostructured yttrium iron garnet (Y3Fe5O12) films during heat treatment of xerogel coatings under various conditions has been studied. How the phase composition, microstructure, and particle size depend on the synthesis parameters has been recognized.
