Title: Determination of yttrium in high temperature refractory oxides by atomic absorption spectroscopy. [In refractory zirconia; 2 to 18% Y/sub 2/O/sub 3/]

Abstract

A rapid method is described for determining yttrium in refractory zirconia using atomic absorption spectroscopy. The sample is fused with a mixture of LiBO/sub 2/ and H/sub 3/BO/sub 3/, and the melt is dissolved in hot dilute HClO/sub 4/. A flame buffer consisting of potassium and EDTA is employed to effect maximum absorbance. The compositions of the standard solutions are matched as closely as possible to the samples. The yttrium absorbance is measured at 410.2 nm using a stoichiometric N/sub 2/O + C/sub 2/H/sub 2/ flame. Sulfate, phosphate, calcium, and magnesium do not interfere. Silica can be removed by fuming with HF before the fusion. Recovery studies show that the procedure is sufficiently accurate to be used for the routine determination of yttrium in samples containing from 2 to 18 percent Y/sub 2/O/sub 3/.
