Abstract
Yttria‐partiaUy‐stabilized zirconia was grown frcm the melt by the arc‐image floating zone technique and annealed at 1700'C. The yttria concentration of the crystal was measured by analytical electron microscopy. The crystal, which contained 8.6 mol% YO1. 5, consists of tetragonal and cubic phases with yttria concentrations of 3.9 and 9.7 mol% YO1.5, respectively. There is a small difference between this result and the composition expected from the ZrO2‐Y2O3 phase diagram.Keywords
