sf6 gas leak System amazonSulfur Hexafluoride (SF₆) is normally prepared in batches through the direct fluorination of high purity sulfur. Sulfur Hexafluoride's relatively high density and inactivity are what make it preferable for employment as an electrical insulator in high voltage transformers, transmission lines, and microwave antennas. It is equally useful as an insulating gas in double windowpane glass.
