Получение композиционных порошков на основе оксидов алюминия циркония из водных растворов

Abstract

The composite powders of zirconia and alumina have been obtained from aqueous solutions by reverse chemical deposition. The composite powders have been recovered from the obtaining suspension after chemical deposition by drying in the oven and spray drying methods (Nano Spray). The results showed that the powders obtained by spray-drying method contains a cubic phase and has a developed surface, indicating that the small particle size. It was also revealed that the powders consist of particular granules with nanoparticles inside. The powders obtained by chemical deposition method submit of monoclinic phase and have an aggregate structure.
