Composition of Individual Microspheres in a Finely Dispersed Fraction from Fly Ash after the Pulverized Combustion of Ekibastuz Coal

A systematic study of the compositions of individual microspheres with sizes of 90 wt % and FeO = 3–6 wt %. Mineral precursors of microspheres of group (3), SiO 2 + Al 2 O 3 < 90 wt % and FeO to 11 wt %, were mixed-layer illite–montmorillonites with a high degree of cationic substitution with ir...

Description
Summary:A systematic study of the compositions of individual microspheres with sizes of 90 wt % and FeO = 3–6 wt %. Mineral precursors of microspheres of group (3), SiO 2 + Al 2 O 3 < 90 wt % and FeO to 11 wt %, were mixed-layer illite–montmorillonites with a high degree of cationic substitution with iron and Fe 3+ included into interlayer sites.
