Abstract

ABSTRACT: Ammonium polyacrylate was adopted for the first time to fabricate nanosized Nd:Y2 O3 powders with good dispersity through solution-combustion method. Results indicate that cubic Y2 O3 can be synthesized at a relatively low temperature (300°C) and that the crystallinity of powder increases with increased calcination temperature. TEM observations reveal that the influence of improve with increased organic-fuel dosage. Well-dispersed Nd:Y2 O3 particles with a narrow size distribution of 20–40 nm can be obtained when the mass ratio of ammonium polyacrylate to yttrium nitrate is 0.5:1. Therefore, ammonium polyacrylate is a new fuel that can be used to prepare well-dispersed Nd:Y2 O3 nanopowders.
