The thermal behaviour of muds and clays
for pelotherapic purposes is a very important parameter because its directly
relation with the therapeutic action of peloids. Usually common clays
are used for maduration in pelotherapy but rarely are used pure clays
as bentonites or sepiolite. Under study in this work are the thermal properties
of almost pure samples of Al-bentonite (montmorillonite), Mg-bentonite
(saponite) and sepiolite, and their comparison with three common clays
composed of mixtures of kaolinite, illite and smectite with other silicates
and carbonates. The samples have been characterized by means of mineralogical
techniques (XRD) but also by chemical analysis (XRF, AA), microfabric
studies (SEM) and physical and physico-chemical determinations (granulometry,
BET surface area, plasticity index, water absorption and CEC). Results
indicate noteworthy differences between common clays and pure clays, especially
with Mg-bentonite. Besides water absorption capacity other physical and
physico-chemical properties seem to play an important role in the cooling
kinetic and therefore in the selection of candidate clays for pelotherapy.
