I am looking for reliable kinetic data of tungsten oxides volatilization process. More specifically reaction of tungsten oxides (metallic tungsten) with steam.
The following literature may be useful for your research
Weight change and oxygen consumption measurements were used to study the kinetics of oxidation of tungsten from 1150° to 1615°C at oxygen pressures of 2–100 Torr. The data were collected in a static type reaction system. Volatilization of tungsten trioxide above 1100°C changed the nature of the oxidation reaction for temperatures between 1100° and 1250°C. At 1150°C and 76 Torr oxygen pressure, oxide scale formed and some tungsten trioxide volatilized, while at 1250 °C and 76 Torr oxygen pressure, all of the oxygen reacted to form volatile tungsten trioxide.
