Published in 2020 at "Metallurgical and Materials Transactions B"

DOI: 10.1007/s11663-019-01743-5

Abstract: The effect of basicity and Cr2O3 content on vitrification of the CaO-MgO-SiO2-Al2O3-Fe2O3-Cr2O3 system during a melt-quenched process and the crystallization and mineralogical evolution of the obtained glasses were investigated. X-ray diffraction (XRD) analysis of the… read more here.

Published in 2019 at "Journal of hazardous materials"

DOI: 10.1016/j.jhazmat.2019.120977

Abstract: Uranium-enriched coal ash (CA) receives a significant attention as a supplementary nuclear resource also due to its potential environmental risk. Combining with CA, the changing trend of uranium occurrence in synthetic coal ash (SCA) was… read more here.
