Abstract
A simple stepwise complexometric method with EDTA has been developed for the determination of zirconium and yttrium in a single aliquot solution involving direcfltitration of zirconium at IN HN03 and 90C and of yttrium at pH 5.3 using methyl thymol blue as indicator. Interferences due to Fe, Ti, AI and Cu have been eliminated by masking with acetylacetone. The method has been standardised against synthetic solutions and applied to various zirconia-yttria ceramics and other yttria bearing materials.
