Liquid argon is tasteless, colorless, odorless, noncorrosive, nonflammable, extremely cold cryogenic liquid. Belonging to the family of rare gases, argon is the most plentiful, making up approximately 1% of the earth’s atmosphere. It is monatomic and extremely inert, forming no known chemical compounds.
Features
- Colorless, odorless, cryogenic liquid
- Inert to all materials at all temperatures and pressures
- Heavier than air, argon will collect in low-lying areas, ducts and drains
- An asphyxiant (does not support life)
- Lower thermal conductivity than most other gases
- Easy forming of welding arc without reacting to metal components
- Creates fluid welding pool when combined with other gases
