Abstract:
Sapropels and carbon-mineral composites obtained by thermal treatment of sapropel at various temperatures were studied by X-ray phase analysis (XPA), transmission electron microscopy (TEM), BET and small angle X-ray scattering (SAXS) methods. It was found that the mineral phase in sapropels formed both elongated layered sapropels particles with fractal dimensions and compact large quartz particles. It was demonstrated that heating sapropels at 300°С led to dispersion and stratification of mineral particles in sapropels, but herewith, the organic phase blocked up the pores formed and hinders an increase in the specific surface of the composite obtained. An increase in heating temperature to 600 °С leads to freeing the porous space from the carbon phase and increasing the total specific surface. A further increase in heating temperature to 900 °С gives partial sintering of the mineral phase and transitioning from fractal volumetric structures to surface ones, herewith, the value of the specific surface of composition materials almost does not change.
