Abstract
To verify the oxidation-dehydrogenation reaction induced by heat treatment of ilvaite in air, a crystal from Elba Island, Italy, was selected for annealing experiments and crystal chemical study. X-ray intensity data were collected and structure refinement was performed after each heat treatment (temperatures ranged from 400 to 700 degrees C). Oxidation of Fe (super 2+) as well as loss of H atoms were deduced from examination of the structural changes occurring as the heating temperature was increased.
