gaz sf6 Gas Properties

It is about five times heavier than air, and has a density of 6.1 4kg / m3. It is colorless, odorless and non-toxic. Tests have been carried out replacing the nitrogen content of air by Sulfr hexafluoride (the gaseous mixture consisted of 79 % sf 6 and 24 % oxygen): five mice were then immersed in this atmosphere for 24 hours, without feeling any ill effects.Get price
