1. Description:

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

Purpose: used in high voltage switch for arc extinguishing and large capacity transformer insulation material;It can also be used in particle accelerator and lightning arrester.It can be used as refrigerant in industry because of its chemical stability and non-corrosion to equipment.Also used in reflexes because of its high ability to stop alpha particles;It also ACTS as a reverse adsorbent to replace oxygen from mine coal.

Obtained by the direct combination of elemental fluorine and sulfur.

 

[note] A substance with good chemical stability, thermal stability is still very good above 500℃.Sublimation temperature -63.8℃.
