Sulfur hexafluoride is a colorless, odorless, non-toxic, non-flammable stable gas. It is one of the most chemically inert gases known, remaining stable at temperdatures up to approximately 400°F (204°C) in the presence of most materials. As a typically non-polar gas, it is slightly soluble in water and oil but highly soluble in non-polar organic solvents. When distilled water is saturated with Sulfur hexafluoride, the pH remains unchanged. It serves as a new generation of ultra-high voltage insulating dielectric material. High-purity electronic grade Sulfur hexafluoride is an ideal electronic etchant, typically transported as a liquefied compressed gas.
