Abstract:
A method of making a strontium-containing, metal-oxide ceramic thin film on a substrate, consisting essentially of the steps of: forming a precursor liquid by mixing a strontium pentoxide compound dissolved in a solvent selected from the group consisting of pyridine and a furan solvent, said strontium pentoxide compound having the formula Sr.sub.5 (O)(OCH.sub.2 C(CH.sub.3).sub.3).sub.8 (solvent).sub.5, and at least one metal alkoxide dissolved in a solvent selected from the group consisting of pyridine and a furan solvent, said at least one metal alkoxide selected from the group consisting of alkoxides of calcium, barium, bismuth, cadmium, lead, titanium, tantalum, hafnium, tungsten, niobium, zirconium, yttrium, lanthanum, antimony, chromium and thallium; depositing a thin film of said precursor liquid on a substrate; and heating said thin film in the presence of oxygen to make a strontium-containing, metal-oxide ceramic thin film.
