Abstract

Results are provided for a study of the internal structure of submicron spherical particles in ZrO2–Y2O3 aerosol powders synthesized by ultrasonic atomization pyrolysis. It is shown the sintering potential for these powders is determined mainly by their internal nanostructural parameters, and not the degree of starting powder fineness. It is detected that the activity of submicron nanostructured powders is commensurate with the activity of ultrafine powders. In contrast to the latter, these powders consist of individual particles not joined in stable multiparticle formations, i.e., agglomerates. This simplifies considerably their practical application without loss of quality for the material obtained.
