Влияние способа выделения на структуру и фазовый состав порошков системы Y2O3-Al2O3

Abstract

It is necessary to synthesize powders with a given phase composition, as well as the size and shape of the particles to obtain transparent ceramics based on yttrium-aluminum garnet. These parameters are directly affected by the method of powder separation. In this work, the phase composition and morphology of the particles isolated by filtration and spray drying methods are analyzed. As a result, it can be concluded that these methods allow to obtain powders with a particle size from 0.1 to 100 µm, and the spray drying method allows to synthesize powders with a smaller particle size.
