973-gaz sf6 Gas Analyzer - MBW Calibration AG

Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and fluorine from SF 6 to form decomposition by-products. These include sulfur dioxide (SO 2) and hydrofluoric acid (HF) that are corrosive to the internal components of gas compartments.Get price

The decomposition products of sulfur hexafluoride (sf6 gas

Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.Get price

reaction of decomposition products with water and oxygen are shown in Fig. 2. It can be seen that the major products of the decomposition reaction are sulphur oxides, while others are fluoride compounds. The concentrations of decomposition products are directly dependent on spark conditions and energy. Figure 2. The formation of SF 6Get price
