Data on plasmochemical technology for the production of oxides of different compounds are presented; the process is highly efficient, comprises only a few stages, and does require reagents for precipitation of the salts. The powders that are formed fall into the category of nano-dimensional materials, are chemically active and homogeneous, and constitute solid solutions. A mathematical model of the design of a reactor is presented and its dimensions determined (evaporation of the drops and decomposition of the salt takes 0.05-0.10 s for a distance extending 0.7 m at T = 1200 -1800 K; the process flowchart is also described. Using zirconium oxide as an example, the morphological components of the powders (spheres, fragments of spheres, and films) are illustrated. Promising directions for the application of the newly developed plasmochemical technologies are noted, specifically, mixed uranium-plutonium fuel for nuclear reactors and charge for piezoceramics and structural ceramics.
