Characterization of Coal Combustion Residues Using Transmission Electron Microscopy Technique

Indian coal-based thermal power stations produces huge amount of coal combustion residues. Proper disposal, management and utilization these ashes have always been a challenge before the plant people. In order to find out potential use residues one need explore look deeply into its various characteristic properties. present study residue samples from station eastern India were used for characterizing on basis Transmission Electron Microscopy technique. The micrographs showed that consisted all three viz. crystalline, polycrystalline amorphous phases. found consist single crystal, crystal with hexagonal structure, substances closed packed structure. Concentric circles as seen in diffraction pattern show presence samples. Presence plerosphere can also be some SEM well TEM images. XRD studies crystalline shows CCR are typically formed Si-Al-Fe system traces sodium, potassium, calcium, magnesium, sulphur titanium.
