Synthesis of superconducting oxides by aerosol pyrolysis of metal-EDTA solutions

Article abstract of DOI:10.1016/0025-5408(89)90063-9

Superconducting oxides in the form of powders or coatings are synthesized from aqueous metal/ethylenediamine tetraacetic acid (EDTA) solutions. The solutions are dispersed ultrasonically to form an aerosol of extremely fine droplets in an oxygen carrier stream. The solution aerosol is passed through a tubular high-temperature furnace and converted into submicron-size oxide particles which are collected by a hot ceramic filter or by electrostatic precipitation.
