Abstract

The phase relations in the system ZrO2YF3YO1.5 have been investigated. Solid state reactions were carried out using encapsulated samples to prevent compositional changes. At 1300°C the ternary system contains 2 single-phase regions of tetragonal (T) and cubic (C) phases, 3 two-phase regions of T+YF3, C+YF3 and C+T, and 1 three-phase region of C+T+YF3. The solubility limits determined from lattice parameters were found to be 8.5 mol% YOF along the ZrO2YOF join for the tetragonal phase, and 4.5 mol% YF3 for the cubic phase, respectively.
