Abstract

The possibility of obtaining submicron ceramic powders with a composition of ZrO2 + 12 mol % CeO2 using the ultrasonic spray pyrolysis method is examined. The effects of the technological parameters of the process on the characteristics of powder particles and their sintering abilities are investigated. The structure and mechanical characteristics of polycrystalline ceramics from aerosol powders indicate sufficiently high properties of this material comparable to similar parameters of ceramics from standard ultradispersed powders. However, to obtain this novel type of ceramic, one does not require pretreatment of the initial powder or use of special expensive methods of powder compaction.
