Abstract
A commercially available water-soluble starch derivative was used as the sole organic precursor in the Liquid-Mix synthesis of mixed-cation oxide powders and thin films. The acidified polymer (by nitric acid) was able to complex metal ions through the carboxylate ligands. Loosely agglomerated fine powders as well as dense thin films of complex oxides have been prepared using the same type of polymer. Oxide powders of Cr-doped lanthanum aluminate and yttrium aluminum garnet both crystallized in a single step, without forming any intermediate or second phases, when the amorphous resin intermediates were calcined at 650 °C and 750 °C for 2 hours, respectively. It wasdemonstrated that nitric acid could effectively reduce the viscosity of the polymer-nitrate solution to make it suitable for spin coating process. Dense thin films of Y(8 mol%)-doped ZrO2 were formed on Si and Al2O3 substrates by spin coating the polymeric solution and heating at temperatures below 1000 °C.
