Halogen Lamp
A similar reaction like that of MoO2 is used in halogen lamps. The tungsten is evaporated from the tungsten filament and converted with traces of oxygen and iodine into the WO2I2, at the high temperatures near the filament the compound decomposes back to tungsten oxygen and iodine.
- WO2 + I2 WO2I2 ΔHrxn < 0 (exothermic)
