Abstract
In this study we observed microscopic characteristics of asbestos at different temperatures for different periods of exposure of asbestos containing material (ACM) using X-ray diffraction (XRD) and polarizing light microscopy (PLM). We observed the destruction of chrysotile crystal structure starting at 600℃ using XRD and using PLM the Chrysotile fibers were heated at 1100℃ for ten minutes resulting in parallel and perpendicular refractive indexes of 1.650 and 1.658 respectively. The sign of elongation was also changed from positive to negative. The results observed in this study may be useful for the quantitative analysis of asbestos which were denatured by the exposure to fire.
Key Words: Asbestos, Chrysotile, X-Ray Diffraction (XRD), Polarizing Light Microscopy (PLM)
