Cylinder Gas 5n C4f8 Gas Electronic Grade 99.999% Octafluorocyclobutane

Product Description

Octafluorocyclobutane (C4F8) is a colorless and odorless gas that belongs to the family of perfluorocarbons (PFCs). PFCs are synthetic compounds that consist entirely of carbon and fluorine atoms. Octafluorocyclobutane is primarily used as a dielectric gas in various electrical applications, such as in semiconductor manufacturing and plasma etching processes.

Here are some key properties and applications of octafluorocyclobutane gas:

Properties:

1. Chemical Formula: C4F8
2. Molecular Weight: 200.03 g/mol
3. Boiling Point: -3.7°C (-19.3°F)
4. Melting Point: -150°C (-238°F)
5. Density: 9.03 g/L at 25°C (77°F)

Applications:

1. Plasma Etching: Octafluorocyclobutane is widely used as a feed gas in plasma etching processes in the semiconductor industry. It is particularly effective for etching silicon dioxide and silicon nitride films.
2. Cleaning Agent: The gas is used as a cleaning agent in the electronics industry to remove organic and inorganic contaminants from surfaces.
3. Insulating Gas: Octafluorocyclobutane is employed as a dielectric gas in high-voltage electrical equipment, such as gas-insulated switchgear (GIS) and circuit breakers.
4. Heat Transfer Fluid: It can be used as a heat transfer fluid in certain applications due to its high thermal stability and low boiling point.
5. Calibration Gas: Octafluorocyclobutane gas is utilized as a calibration gas in gas analyzers and environmental monitoring equipment.

It's important to note that perfluorocarbons, including octafluorocyclobutane, have a high global warming potential (GWP) and contribute to climate change. Therefore, their usage and emissions are subject to regulation and control to minimize their environmental impact.
