Abstract

The oxidation kinetics of Rh were measured in air at 1 atm. in the temperature range 600–1000°C. The oxidation weight gain proceeds logarithmically at the lower temperatures (600°C, 650°C) followed by a transition to power law behavior at the higher temperatures (≥800°C). The logarithmic growth kinetics result from thickening of a hexagonal Rh2O3 scale. The transition from logarithmic to power law growth kinetics occurs in the range 700–800°C, and reflects thickening of hexagonal and orthorhombic Rh2O3 scales. Above 800°C, the growth kinetics result from thickening of a predominately orthorhombic Rh2O3 scale. At 1000°C the oxide becomes volatile, leaving the metal surface exposed.
