Sulfur hexafluoride gas is widely used in electronics,electricity,laser,medical treatment,refrigeration,chemical industry,non-ferrous metal smelting and other industries because of its stable chemical properties,strong arc extinguishing performance and non-flammability.So is this gas,which is in high demand,expensive?

　　As with general commodities,the production method determines the production cost of sulfur hexafluoride gas,so the price of sulfur hexafluoride is closely related to the preparation process.At present,sulfur hexafluoride can be produced by electrolysis method and direct chemical method.The price of gas varies greatly depending on the method of production.

　　Direct chemical method is divided into:fluorine gas and solid sulfur,molten sulfur,and sulfur vapor three kinds,but fluorine gas and solid sulfur direct reaction,exothermic reaction is more intense,but also will produce a lot of unnecessary by-products,increase the subsequent treatment cost of sulfur hexafluoride gas.

　　Due to the reaction of fluorine gas and molten sulfur,the temperature is better controlled,so it is the production method adopted by most sulfur hexafluoride manufacturers in China.As long as the fluorine gas and molten sulfur liquid surface are introduced in parallel direction,high reaction yield can be maintained.This method can be used on a large scale and indirectly reduces the price of the gas.If you have any questions,welcome to consult!For more information,call 139-4929-0069
