Abstract

A ceramic porous filler obtained from intershale clay and oil sludge, which are pollutants in the environment, is the object of this study. The distribution of iron ions is revealed during the firing of the porous filler with a Mossbauer effect. The transformations of ferrous compounds in redox processes on the surface and in the middle of the samples containing high amount of iron oxide are considered. The experiments showed that the calcined ceramic samples have a zonality: the surface of the samples containing less than 6% of Fe2O3 is lighter than that of the inside part, the surface of the samples containing more than 8% of Fe2O3 is light cherry in color, and the interior part is dark cherry in color. The proposed composition for the production of a porous filler is innovative to decrease the negative impact of toxic wastes on the environment, the novelty of which is protected by a patent of the Russian Federation.
