Scanning photoacoustic microscopy of coal

Scanning photoacoustic microscopy was utilized to investigate the possibility of characterization of coal by its thermal properties. A band of iron pyrite was clearly observed photoacoustically as were CO 2 and argon-ion laser pyrolyzed areas. The change in photo-acoustic data due to laser pyrolysis...

Summary:Scanning photoacoustic microscopy was utilized to investigate the possibility of characterization of coal by its thermal properties. A band of iron pyrite was clearly observed photoacoustically as were CO 2 and argon-ion laser pyrolyzed areas. The change in photo-acoustic data due to laser pyrolysis was analyzed and confirmed by a scanning electron microscope with X-ray fluorescence capability.
