Abstract
The synthesis of hydrolytically active heteroligand precursors of the composition [M(O2C5H7)x(iOC5H11)y] (M = Zr4+ and Y3+) using zirconium and yttrium acetylacetonates was investigated. It was shown that the reactivity of the obtained precursors in hydrolysis and polycondensation depends on the composition of the coordination sphere. It was studied how thin films of their solutions are applied by dip coating to the surface of Al2O3 substrates with platinum interdigital electrodes and a microheater. A study was made of the effect of the crystallization conditions and thickness of the oxide coatings of the composition 8 mol % Y2O3–ZrO2 on their microstructure and sensor characteristics in oxygen detection.
