| Abstract: | Structural changes accompanying thermal transformation in a chrysotile asbestos sample of Indian origin upto a temperature
of 900°C have been investigated by x-ray method. The changes in lattice parameters have been systematically measured by applying
a least square refinement technique and the crystallite size and strain defects at different stages have been estimated by
line profile analysis of the diffraction peaks. The present study also confirms the earlier results on stepwise transformation
of chrysotile fibres. This sequence of transformation has been explained assuming two different types of crystallites as reported
in kaolinite. |
