Popis:	The composition and structure of the microspheric aluminosilicates of Combined Heating and Power Plants (CHРP) ashes is studied with the help of modern physical-chemical methods (XRD, scanning electron microscopy, BET, elemental and chemical analysis). The activity of microsphere-based catalysts for the reaction of Na2SO3 oxidation by oxygen is also studied by kinetic and potentiometric methods. By means of EPR and Möessbauer spectroscopy it is concluded that iron ions into the composition of cenospheres exist in two states – Fe3+ and Fe2+, thus, the iron (III) is in the form of solitary ions in an aluminosilicate matrix in the range of the iron content 3-4 mass %.
