Kinetics Model of the Thermal Oxidation of Indium Powder

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.
