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 90°C 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.
