A peroxopolytitanic acid (Ti-IPA) solution was prepared through a direction reaction of H2O2/NH3 and metallic titanium powder. A BaTi2O5 precursor powder was prepared by a reaction of the prepared Ti-IPA and a Ba(OH)2 aqueous solution. The obtained BaTi2O5 precursor powders were heat treated at 1000...
