Abstract
Mixed metal oxide electroceramics are produced from dissolved metal oxides using aqueous processing. For example, zirconates and titanates are manufactured from titania and zirconia using aqueous processing by forming an ammonium titanium complex, or an ammonium zironium complex, which can then be further reacted to release ammonia and form a metal titane or metal zirconate precursor. The precursor is then pyrolyzed to the corresponding oxide, e.g. barium and/or strontium titanate.
