| Abstract |
| Structural differences occurring in vermiculite minerals of different
origin are brought out in this paper. Peaks obtained in DTA and
TGA are attributed to the structural modifications occurring in the
minerals due to heat-treatment. The thermal domains for existence
of both phyllosilicate and intermediate phases are correlated to the
charge density of the mineral. Exfoliation characteristic of the
minerals vis-a-vis charge density is also discussed. |
