Abstract
The sample of zirconium-yttrium oxide powder was digested at high-temperature and highpressure,then Y and 6impurity elements(Al,Fe,Na,Mg,Hf and Si)were determined using ICP-AES.Analytical spectral lines of 396.152,238.204,589.592,279.553,277.336,288.158 and 371.029 nm were chosen for the determination of Al,Fe,Na,Mg,Hf,Si and Y,respectively.Linear ranges were within 75.0mg·L-1 for Y,and within 30.0mg·L-1 for the other 6impurity elements,with detection limits(3s)in the range of 0.2-2μg·g-1.The proposed method was applied to the analysis of zirconium-yttrium oxide powder,giving values of recovery and RSD′s(n=5)of 80.0%-120%and 3.1%-5.2%,respectively.
