Résumé:

The complete oxidation kinetics of indium powder in air has been studied from thermogravimetric studies under isothermal conditions in the range 858-1173 K. The influence of particle size was analyzed in the 25-375 lm range. We succeeded in carrying out the full oxidation of the powders far above the indium-metal melting point (429.75 K) without apparent coalescence of the particles through the presence of a thin In2O3 layer which confines the liquid metal during the oxidation process. The apparent activation energy obtained from the Arrhenius law was 62.2 kJ mol-1.
