For coal gangue, about 20% of mass loss was found in the temperature range of 400–900 °C and there was no further mass loss as the increased temperature. This might be mainly attributed to the dehydroxylation reaction that the kaolin (Al 2 Si 2 O 5 (OH) 4) phase in the coal gangue was converted into the metakaolin (Al 2 Si 2 O 7) phase.
