Thermal inertization of amphibole asbestos modulates Fe topochemistry and surface reactivity
This study discloses the morphological and chemical-structural modifications that occur during thermal degradation of
amphibole asbestos. Low-iron tremolite and iron-rich crocidolite were heated at temperatures ranging from r.t. to
1200 °C. Heating promoted a complex sequence of iron oxidation, migration and/or clustering and, finally, the formation
of brittle fibrous pseudomorphs consisting of newly formed minerals and amorphous nanophases. The effects
