Abstract

Phase assemblages of the K–Fe–Se ternary system (x K < 33.3 %) were obtained by powder X-ray diffraction (PXRD). The superconducting phase KxFe2-ySe2 has not been detected in the phase assemblages. Based on the microscopic image and magnetic susceptibility of the samples with different annealing times, we demonstrate that KxFe2-ySe2 is the metastable phase, which only appeared at the beginning of annealing process, and converted to the non-superconducting phase after the long-time annealing.
