Abstract
Compositions are described which are useful in many applications such as fire extinguishing or refrigeration. The compositions may include a hydrochlorofluorocarbon such as 2,2-dichloro-1,1,1-trifluoroethane, a dispersant such as CF3I, and an inert gas such as argon, and may in some embodiments be held under pressure. For example, some fire extinguishing compositions may be composed of 2,2-dichloro-1,1,1-trifluoroethane, CF3I, and argon.
