title = "Phase transformations in fergusonite-type rare earth tantalates",
abstract = "A range of samples, RETaO4 (RE = Nd, Sm, Gd, Dy, Er, Ho) were synthesized via solid state and solution routes. Two modifications exist at room temperature with the structure being dependent on synthesis method and heat treatment. M-Fergusonite (I2/a) is formed at higher temperatures via solid state methods, whilst the M'-Fergusonites (P2/a) are made at lower temperatures through solution routes. Both modifications transform at high temperatures to a tetragonal phase (I41/a). For M phases this is second order and reversible, whilst for M'-phases the transformation is first order and irreversible. The phase transition behavior has been investigated through high temperature DSC and in situ synchrotron XRD measurements.",
