Electronic Industry Argon 99.999% purity Ar
Ar,The most common source of argon is an air separation plant. Air contains approx. 0.93% (volume) argon. A crude argon stream containing up to 5% oxygen is removed from the primary air separation column through a secondary (“sidearm”) column. The crude argon is then further purified to produce the various commercial grades required. Argon can also be recovered from the off-gas stream of some ammonia plants.
Argon is a rare gas widely used in industry. Its nature is very inactive, and it can neither burn nor help to burn. In the aircraft manufacturing, shipbuilding, atomic energy industry and machinery industry sectors, argon is often used as welding protection gas for special metals, such as aluminum, magnesium, copper and its alloys and stainless steel, to prevent the welding parts from being oxidized or nitrided by air.

Safety Instructions
Emergency summary: No gas, the cylinder container is easy to overpressure when heated, there is a risk of explosion. Cryogenic liquids can cause frostbite. GHS Hazard Category: According to the Chemical Classification, Warning Label and Warning Specification series, this product is a gas under pressure – compressed gas.
Warning word: Warning
Danger information: Gas under pressure, if heated can explode.
Precautions:
Precautions: Keep away from heat sources, open flames, and hot surfaces. No smoking in the workplace.
Accident response: cut off the leakage source, reasonable ventilation, accelerate diffusion.
Safe storage: Avoid sunlight and store in a well-ventilated place.
Disposal: This product or its container shall be disposed of in accordance with local regulations
Physical and chemical hazards: compressed non-flammable gas, the cylinder container is easy to overpressure when heated, and there is a risk of explosion. High concentration inhalation can cause suffocation.
Exposure to liquid argon can cause frostbite.
Health hazard: Non-toxic at atmospheric pressure. When the high concentration, the partial pressure is reduced and the chamber breath occurs. The concentration is more than 50%, causing severe symptoms; In more than 75% of cases, death can occur within minutes. When the concentration in the air increases, the first is accelerated breathing, lack of concentration, and ataxia. This is followed by fatigue, restlessness, nausea, vomiting, coma, convulsions, and even death. Liquid argon can cause skin frostbite: Eye contact can cause inflammation.
Environmental harm: No harm to the environment.
