Abstract
Peak area due to dehydroxylation of some kaolinite fractions has been determined
from their DT A thermograms and correlated with their surface area. It has been observed
that in spite of their identical degree of crystallinity, their peak area, except
in the finest fraction, does not decrease with increase of their surface area. This phenomenon
has been explained as due to the existence of a large surface area due to edges
whose adjacent OH- ions require less energy to be driven off than the others.
