Abstract :
High-temperature G0 polymorph of Rb2KMoO3F3 has been prepared by melt solidification. Micromorphology and chemical properties of the final product were evaluated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The elpasolite-related crystal structure of G0-Rb2KMoO3F3 has been refined by Rietveld method at T = 298 K (space group Fm-3m, a = 8.92446(8) Å, V = 710.76(1) Å3; RB = 3.55%). Ferroelectric G1-Rb2KMoO3F3 polymorph, earlier reported at T < 328 K, is not found at T = 298 K.
