The thermal reaction of SF 6 with tungsten powder was investigated by thermogravimetry (TG) and differential scanning calorimetry (DSC), combined the characterization solid decomposition products SEM, EDS, XPS Raman. Based on above experiments, a two-stage process proposed: first stage is surface vulcanization W+SF →S 2 , mainly taken place at 600 °C, activation energy valued 152.8 kJ·mol -1 ac...
