Mechanism and Structural Analysis of the Thermal Activation of Coal-Gangue

This paper presents a study of the thermal activation of coal-gangue. The samples were tested and analyzed using Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), Magic Angle Spin Nuclear Magnetic Resonance (MAS NMR), Scanning Electron Microscopy (SEM), and Atomic Emission Spectroscopy (ICP-AES). Results indicate that the degree of coal-gangue activation varies with variations in the phase structure and coordination of aluminum at different temperatures.
