sulfur hexafluoride Microwater sensor in south africa

Uranium hexafluoride does not react with oxygen, nitrogen, carbon dioxide, or dry air, but it does react with water or water vapor. For this reason, UF 6 is always handled in leak tight containers and processing equipment. When UF 6 comes into contact with water, such as water vapor in the air, the UF 6 and water react, forming corrosive hydrogen fluoride (HF) and a uranium fluoride compound
