Sulfur Hexafluoride (SF6)

1.molecular formula:SF6   CSA NO.: 2551-62-4

2.molecular weight:146.06

3.main characteristic: The SF6 is a kind of achromat, have no smelly and not poisonous with have no caustic of compoundp.Presenting a gas under the normal temperature normal is incombustibility gas, the nonmetal oxide of chemistry best stability.In order to having good chemistry and hot stability, under the sistuation that assure purity, 500 °C temperatures down can't are resolved, either.In order to having good insulated performance and reducing arc capability, even if under the arc electric take place moment resolution, ionization, but in the arc electric decrease behind can also very quickly recovery arrive original of stabilization state, so make use of its high chemistry stability and outstanding electricity insulated characteristic, broadly use at the electricity industry and the extra - high tension lnsulation material.In addition it still has coefficient of heat transfer big, air – coolingphysical property:

5.Main use:

(1)Extensively Be applied to high pressure and win the lnsulation material of piezoelectric machine equipment and reduce arc dielectric;

(2)BE more available than metal smelting production technical to defend oxideizing agent;

(3)Used for a weather to show a Zong experiment and show a Zong agent, make air - cooling technical system air - cooling the agent and thermal carry a body;

(4)Used for X on the medical treatment-shoot the insulated gas of wire device;

(5)It is more available than single crystal Huo of production and foundation theory science search etc..
