X-Ray Diffraction Analysis of Bottom Ash Waste after Plasma Treatment

Abstract

Abstract. The paper deals with the plasma-chemical synthesis of melts produced from the bottom ash waste for the production of new construction materials with enhanced performance characteristics. Phase composition of the plasma-treated bottom ash waste is detected by the Xray diffraction analysis. The bottom ash waste is a mixture of SiO 2 minerals. The structure and phase composition of this mixture are investigated after the plasma treatment. The obtained results are compared with the original state of the mixture. The identification and the qualitative content of ash waste as a multi-phase system are complicated by the overlapped reflections and a possible existence of the intermediate amorphous phase.

Physiochemical characterization and systematic investigation of metals extraction from fly and bottom ashes produced from municipal solid waste

“…Also, the presence of SiO 2 could be due to the earth’s surface or anthropogenic activities due to the sand uptake of the waste or the erosion of the materials [ 40 ]. These results were in a good agreement with other available data from relatively similar studies including Zhang et al [ 31 ], Bertolini et al [ 37 ], Volokitin et al [ 41 ], Yang et al [ 42 ], Hussain et al [ 43 ], Alam et al [ 44 ], and Wongsa et al [ 45 ].…”
