CAS No. 2551-62-4 Sulfur Hexafluoride Supplier. Characteristics of Sulfur Hexafluoride

Sulfur hexafluoride (SF6) is a synthetic gas that has found numerous applications across various industries. Its CAS number is indeed 2551-62-4. Here are some characteristics of sulfur hexafluoride:

Chemical Properties:
Formula: SF6
Molecular Weight: Approximately 146.06 g/mol
Boiling Point: About −63.8 °C
Melting Point: About −50.8 °C
Physical Properties:
SF6 is a colorless, odorless, non-flammable gas.
It is heavier than air, with a density about five times that of air at standard conditions.
It is non-reactive under normal conditions but can be toxic in high concentrations due to its ability to displace oxygen and cause asphyxiation.
Electrical Properties:
SF6 is known for its exceptional dielectric strength, making it an excellent insulator in high-voltage electrical equipment like circuit breakers, switchgear, and transformers.
Environmental Impact:
SF6 is a potent greenhouse gas, with a global warming potential (GWP) over 20 years that is about 23,500 times greater than CO2.
Due to its long atmospheric lifetime (estimated around 3,200 years), efforts have been made to reduce its emissions and find alternatives where possible.
Applications:
Electrical Engineering: Used as an insulating and arc-quenching medium in high-voltage switchgear and circuit breakers.
Medical Imaging: Used in magnetic resonance imaging (MRI) and computed tomography (CT) scans as a contrast agent.
Metal Casting: SF6 can be used in the casting process to prevent oxidation of molten metals.
Laser Technology: It is used in certain types of lasers.
Handling and Safety:
SF6 should be handled with care to avoid leaks, which could contribute to greenhouse gas emissions.
It is non-toxic in its pure form but can be harmful if it decomposes into toxic byproducts under arcing conditions.
Adequate ventilation and monitoring systems are required when working with SF6 to ensure worker safety and environmental protection.
