N2 - Using muon spin rotation and infrared spectroscopy, we investigated the recently discovered superconductor K0.73Fe1.67Se2 with T-c approximate to 32 K. We show that the combined data can be consistently described in terms of a macroscopically phase-segregated state with a matrix of similar to 88% volume fraction that is insulating and strongly magnetic and inclusions with an similar to 12% volume fraction, which are metallic, superconducting, and nonmagnetic. The electronic properties of the latter, in terms of the normal state plasma frequency and the superconducting condensate density, appear to be similar as in other iron selenide or arsenide superconductors.
