摘要：

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