Description

The physical and technical conditions for reproducible production of nanodispersed yttrium aluminum garnet (Y3Al5O12, YAG) and yttrium oxide (Y2O3) powders by chemical coprecipitation have been investigated. It is established that the obtained YAG nanopowders have enhanced reactivity, which significantly decreases the temperature range of interaction in the Y2O3-Al2O3 system in comparison with ceramic synthesis. It is shown that vacuum heat treatment may lead to reversible transformation of the YAG crystal structure from cubic to tetragonal.
