Title: Production of Y{sub 3}Al{sub 5}O{sub 12} and Y{sub 2}O{sub 3} nanopowders for optical ceramics

Abstract

The physical and technical conditions for reproducible production of nanodispersed yttrium aluminum garnet (Y{sub 3}Al{sub 5}O{sub 12}, YAG) and yttrium oxide (Y{sub 2}O{sub 3}) 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 Y{sub 2}O{sub 3}-Al{sub 2}O{sub 3} 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.
