Applications
DescriptionOctafluorocyclobutane is a colorless gas.Molecular weight = 200.03; Boiling point = -6℃;Freezing/Melting point = -41℃. Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 0, Reactivity 0. Slightly soluble (slighthydrolysis).
UsesRefrigerant; 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.
