Abstract
The thermal decomposition of ammonium metavanadate, NH4VO3, has been s tudied by differential scanning calorimetry (DSC), mass spectrometry ( MS) and X-ray diffraction (XRD) in the temperature range 50-500 degree s C. Different experimental conditions (heating rate and atmosphere) h ave been explored in various combinations. Different types of reaction mechanisms leading to crystalline V6O13 and V3O7 can be identified. T he formation of V2O5 is also discussed briefly.
