Abstrakt: Natural samples of exogenous silicites are investigated by a combination of physical methods (X‑ray phase analysis, atomic-force microscopy, optical microscopy, scanning electron microscopy, optical transmission). The samples contain a small amount (~1%) of water and consist of chalcedony nanoparticles with a size of 22–68 nm, which form a complex hierarchically organized structure. [ABSTRACT FROM AUTHOR]
