Allgemeine Beschreibung
Carbon tetrafluoride (CF4), also known as tetrafluoromethane, belongs to the class of fluoromethanes. It can be prepared by the reaction of silicon carbide with fluorine. It is used as a refrigerant.
Anwendung
Carbon tetrafluoride can be used in fluorine chemistry for the preparation of organofluorine compounds. It is also used as a solvent in low-temperature reactions . During the manufacture of electronics devices, CF4 plasma is widely used to etch a variety of materials.
Verpackung
Packaged in carbon steel lecture bottles with CGA 110F/180M Al-Si-Bronze needle valve.

We present results for the isothermal adsorption kinetics of methane, hydrogen, and tetrafluoromethane on closed-ended single-walled carbon nanotubes. In these experiments, we monitor the pressure decrease as a function of time as equilibrium is approached, after a dose of gas

Grand canonical Monte Carlo simulations are reported for low molecular weight perfluorocarbons (C2F6 and CF4) and their dilute (10% molar) mixtures in N2 adsorbing unto slitlike graphite pores. Adsorption isotherms and selectivity plots are shown for various temperatures, pressures, and

The production of 18F electrophilic reagents via the 18O(p,n)18F reaction has been investigated in small-volume target bodies made of aluminum, copper, gold-plated copper and nickel, having straight or conical bore shapes. Three irradiation protocols-single-step, two-step and modified two-step-were used for

The inflammatory cell response of tetrafluorocarbon (CF4) plasma surface modification of poly(methyl methacrylate) intraocular lenses (IOLs) was investigated in vitro. After two hours of lens contact with human granulocytes, scanning electron microscopy showed significantly less cell activation and granulocyte adhesion
