Electronic Grade 99.999% 5n Cylinder Gas C4f8 octafluorocyclobutane

Product Description

Octafluorocyclobutane (C4F8) is a chemical compound composed of carbon and fluorine. It is a perfluorinated cyclobutane with the molecular formula C4F8. Here are some additional details about octafluorocyclobutane:

1. Structure: Octafluorocyclobutane consists of a four-membered ring composed of carbon atoms, with each carbon atom bonded to four fluorine atoms. The molecule is fully saturated with fluorine, meaning that all available bonding sites on the carbon atoms are occupied by fluorine atoms.

2. Physical properties: Octafluorocyclobutane is a colorless gas at room temperature and pressure. It has a boiling point of around -16.3 °C (-1.3 °F) and a melting point of around -97.9 °C (-144.2 °F). It has a relatively low density and is soluble in some organic solvents.

3. Chemical properties: Octafluorocyclobutane is a chemically stable compound with low reactivity. It is non-flammable, non-toxic, and non-corrosive. It is resistant to most chemical reactions and is generally inert under normal conditions.

4. Applications: Octafluorocyclobutane has various applications, primarily in the electronics industry. It is commonly used as a dielectric gas in plasma etching processes for semiconductor manufacturing. It is particularly effective in etching silicon dioxide (SiO2) and silicon nitride (Si3N4) materials. Octafluorocyclobutane is also used in the production of photovoltaic cells, flat-panel displays, and other electronic devices.

5. Environmental impact: Like other fluorinated gases, octafluorocyclobutane has a high global warming potential (GWP). It has a significantly higher GWP than carbon dioxide (CO2) over a 100-year time frame. Therefore, it is important to manage and minimize the emissions of C4F8 and other similar compounds to mitigate their impact on climate change.

It's important to note that when working with octafluorocyclobutane or any other chemicals, appropriate safety measures and handling protocols should be followed to ensure personal safety and prevent environmental harm.
