| Physical Description | Octafluorocyclobutane is a colorless nonflammable gas. It may be harmful by asphyxiation. Exposure of the container to prolonged heat or fire can cause it to rupture violently and rocket. It is used to make other chemicals.Gas VaporLiquidNon-flammable and non-toxic gas[Merck Index] Colorless odorless liquefied gas[Air Liquide America MSDS] |

Anwendungen & Verwendung
Verwenden
Refrigerant; heat-transfer medium.Halocarbon 318 is used for plasma etching. When it is exposed to the RF field generated in the etching process, a gas plasma is produced that will etch silicon compounds with excellent selectivity.
