    Abstract

    Comprehensive X-ray diffraction study on the sub-solidus phase diagram in Pr6O11-La2O3-CuO system firstly revealed a new phase of Pr2-xLaxCuO4 for 1.35 <x <1.5. The phase has a tetragonal symmetry similar to the well-known T′-type structure (0 <x <0.9). However, the lattice constants of both a and c are clearly distinct between the two tetragonal phases. The new phase coexists with the T′-phase for 0.9 <x <1.3 and with the orthorhombic T-phase for 1.5 <x <1.6. The sintered pellet of the new phase instantly transforms into fine powder (∼10 μm) upon cooling from synthesized temperature to room temperature without any compositional phase separation.
