Activity and structure of calcined coal gangue
Journal of Wuhan University of Technology-Mater. Sci. Ed., 2007 Coal gangue was activated by means of calcination in seven temperature ranges. Systematic research was made about activation mechanism and structural evolution. Glycerin-ethanol method, SEM, MIP and XRD were used to determine the variation of structure and activation of coal gangue during the calcination.
