Product Description

CAS 2551-62-4 SF6 Liquefied Compressed Gas Oxidation Etching And Wafer Cleaning

Description:

Electronic Gases Sulfur hexafluoride (SF6) is a colorless in-noxious and non-flammable gas at atmospheric temperature.. It is chemical stable with good insulation.

Sulfur hexafluoride (SF6) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas, which is an excellent electrical insulator.[4] SF6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.

During the etching process of the radio frequency environment and the gas phase insulator and the physical industry under the high strength, the six fluoride is provided with the free radical of fluorine and sulfur. The representative application is oxidation etching, etching and wafer cleaning. Six sulfur fluoride can also be used for tungsten etching, the product is volatile and easy to be separated from the wafer. High purity of six sulfur fluoride in reducing the impact of by-products and improve the etching effect has played a very good control.

It is a hypervalent molecule. Typical for a nonpolar gas, it is poorly soluble in water but quite soluble in nonpolar organic solvents. It is generally transported as a liquefied compressed gas.

This substance undergoes chemical reactions only under relatively severe circumstances. They are resistant to ignition, although they may become flammable at very high temperatures. They may be resistant to oxidation reduction, except in the most severe conditions. These materials may be nontoxic. They can asphyxiate. Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container [Handling Chemicals Safely 1980].

Applications:

Electrical Industries Circuit Breaker	leak detection and as a gaseous dielectric for transformers, condensers and circuit breakers,high-voltage transmission line, CIS, large cable coil, mutual inductor, lightning arrester.
As an inert gas	For the casting of magnesium.as an etchant in the semiconductor industry
As an inert filling	Insulated glazing windows.
Dielectric medium	SF6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.
Medical use	SF6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations in the form of a gas bubble.SF6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein.
Tracer compound	Sulfur hexafluoride was the tracer gas used in the first roadway air dispersion model calibration; this research program was sponsored by the U.S. Environmental Protection Agency and conducted in Sunnyvale, California on U.S. Highway 101.Sulfur hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing.
