Abstract

By means of Mössbauer spectroscopy, scanning electron microscopy and thermodynamic analysis methods a detailed study of composition, morphology and properties of ash microspheres obtained at combustion of three coals (Irsha-Borodinsky, Kuznetsky and Ekibastuzsky) has been carried out. The ranges of composition of microspheres suitable for solidification of liquid radioactive waste in the form of iron-phosphate (36-94 wt.% Fe2O3) and aluminosilicate (2-20 wt.% Fe2O3) ceramics have been determined. The possibility of obtaining new materials on the basis of coal dust cenospheres and their application for immobilization of liquid radioactive waste has been shown.
