Abstract
In this study, we investigated the kinetics and products of the oxidation of MoSi2 powder with an average particle size of 1.6 μm at 900°, 1000° and 1100°C, using a small sample size of 0.5 g. Such a small sample size allowed us to minimize the effect of oxygen transportation through the powder volume, while maintaining a good relative weighing accuracy. X-ray diffraction of oxidized samples indicated the formation of Mo5Si3 and Mo metal. Analysis of the Oxidation kinetics suggested that gaseous MoO3 formed initially and amorphous SiO2 film later. The oxidation kinetics and products observed in this study differ from those reported in an early study, in which a larger sample size was used.
