White globules of solid sulfur modification are obtained from saturated aqueous solutions. The chemical composition, morphology, and structure of the white sediment are investigated by means of X-ray fluorescence analysis, scanning electron microscopy, and high resolution transmission electron microscopy. It is shown that the white sediment contains an unknown modification of globular hexagonal sulfur with globule sizes of 5–10 μm and interplanar distances of 0.45, 0.29, and 0.15 nm. A single absorption band at 880 cm−1 is found in the Raman scattering spectra of the saturated solutions above the sediment. It is suggested that the white sediment consists of condensed S2 phase.
