Electric Dispersion Reactor The electric dispersion reactor (EDR) is a multiphase electrodispersion precipitation reactor used for the synthesis of ultrafine particles for the production of precursor powders of advanced ceramic materials. This technology employs electric-field-enhanced atomization of conductive liquids in a nonconducting liquid to form reactive microdroplets in the size range of 0.1 to 10 micrometers. The EDR has been employed, using metal alkoxide and metal salt solutions, to synthesize ceramic precursor powders (including sillica, alumina, zirconia, and 1:2:3 yttrium-barium-copper) with chemical homogeneity on the submicrometer level. The EDR allows control and modification of particle morphology; it has been shown to be a viable means for production of microspheres and porous spherical shells.
