AbstractSub-micron sized metal oxide particles were formed via aerosol decomposition using single-source mixed metal-organic precursors specifically designed to decompose at low temperatures. The advantage of these single-source precursors over mixtures of individual precursors is that each particle contains a fixed stoichiometry and molecular level homogeneity. Furthermore, the loss of volatile intermediates (such as PbO) may be avoided. Aerosol processing routes can produce uniform sub-micron sized powder that can be sintered at low temperatures for various thin film and membrane applications. The single-source precursors were prepared in pyridine by reaction of divalent metal α-hydroxycarboxylates of general empirical formula A(O2CCMe2OH)2 (where A = Pb, Ca, Sr, Ba; Me = methyl) with metal alkoxides (for example, Ti(O-i-Pr)4) with the elimination of two equivalents of alcohol. These species were then hydrolyzed in solution and yellow powders were isolated by removal of the pyridine solvent in vacuo. These powders were dissolved in water and used to prepare mixed metal oxide powders via spray pyrolysis. Phase-pure submicron-sized particles of PbTiO3 and BaTiO3 were produced at temperatures of 600-900 °C. The particles were hollow, ranged in size from 0.1 to 1 μm and consisted of 30-50 nm crystallites.
