Abstract

Two simple and sensitive spectrophotometric methods for the determination of zirconium and yttrium in YSZ specimens have been suggested in this study. The calibration graph for zirconium and yttrium was linear in the range of 0.08-0.4 and 0.1-0.6 μg/mL, respectively. The proposed analytical procedure was applied for the determination of zirconium and yttrium in the YSZ samples synthesized by aqueous sol-gel method. The relative standard deviation (RSD) for zirconium was in the range from 0.6 to 4.5%, for yttrium it was from 0.6 to 3.6%. The achieved results demonstrated that the suggested procedure could be successfully applied for the analysis of YSZ powders with satisfactory accuracy.
