Abstract
Transparent Nd:Y2O3 ceramic was obtained by sintering mono-sized spherical powder. The powder was prepared by homogeneous precipitation method in aqueous media using urea to regulate the pH. The structure and morphology of the powder were investigated by TG–DTA, XRD, SEM and IR spectrum. The effect of aging temperature, time, and the concentration of urea, [Y3+], and [Nd3+] were investigated. Results showed that the obtained precursor was R2(OH)CO3·H2O (R = Y, Nd), and the least size of mono-sized spherical yttria particles was 72 nm by a microwave oven method after calcinations at 850 °C for 4 h. After dry press and CIP, the particles accumulated closely, and no defects can be detected in the green body.
