A systematic investigation of the relationship between the composition, structure, and physicochemical properties of narrow fractions of microspheres―ferrospheres and cenospheres separated from all known types of fly ashes of power-generating coals―has been performed for the first time.

It has been shown that microspheres separated from fly ashes of energy coals are promising for the use in the design of new functional materials: catalysts and diffusion membranes intended for the processing of the helium-bearing natural gas from the Eastern Siberia with the aim of producing ethylene and helium as target products, as well as sorbents for solidification of liquid radioactive wastes in the mineral-like form.
