But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earthatmosphere.Get price

Effects of O-2 and insulating gas vibrational energy on the rate

Rate constants for the charge-transfer reaction of O-2 with sf 6 have been measured as a function of the average kinetic energy (KEcm) at several temperatures in a selected-ion flow-drift tube. Increasing kinetic energy is found generally to decrease the reactivity. In the temperature range below 300 K, increasing temperature is found to decrease the rate constants; above 300 K the rateGet price
