Argon Gas 3n - 5n High Purity 99.999% Industrial Grade Electronic Grade Medical Grade Certified Factory From China

Argon, the third most abundant gas in the air (about 0.93%), is an indispensable inert guardian in the industrial and technological fields. It is silent yet builds protective barriers for countless critical processes, ensuring quality, enhancing efficiency, and safeguarding safety. Choosing our high-purity argon is choosing stability, purity and reliability.

Key physical and chemical properties:
Properties Values/Descriptions Importance
State and Appearance Colourless, odourless, tasteless gas Unnoticeable under normal conditions
Chemical Properties Highly inert (rare gas) Core value! Non-flammable, non-supportive of combustion, difficult to react
Density 1.784 g/L (air ≈ 1.29 g/L) Heavier than air, tends to accumulate at the bottom of enclosed spaces
Boiling Point -185.9°C Foundation for low-temperature applications
Solubility in Water Extremely low Not easily absorbed by water
Molecular Weight 39.948

Core application areas (where argon excels):

1.The King of Metal Processing:

TIG/MIG welding shielding gas: Core application! It isolates air and prevents the molten metal from oxidizing and nitriding, ensuring smooth, strong and defect-free weld seams. It is particularly indispensable in the welding of active metals such as stainless steel, aluminum and titanium. Icon: Welding sparks.
Stainless steel/special alloy smelting: In the refining processes such as AOD/VOD, nitrogen is replaced to achieve decarburization and oxygen control, thereby improving the purity of the molten steel.
Heat treatment protective gas: During high-temperature annealing and sintering processes, oxygen is isolated to prevent the workpiece from oxidizing and decarburizing, thereby maintaining the surface smoothness and performance.

2.Optoelectronics and Semiconductor Manufacturing:

Crystal growth protective gas: During the growth process of single-crystal silicon, LED blue-sapphire substrates, etc., it prevents high-temperature oxidation and ensures the quality of the crystals.
Semiconductor deposition/etching: As a carrier gas or diluent gas, it participates in key processes such as physical vapor deposition (PVD), chemical vapor deposition (CVD), and plasma etching.
Special lighting filling gas: Used for filling in energy-saving lamps, neon lights, and fluorescent tubes. It works in conjunction with mercury vapor to generate ultraviolet rays, which excite the fluorescent powder to emit light. Icon: Light bulb.

3.Research and Laboratory

Inert atmosphere operation: The glove box and reactor provide a dry and oxygen-free environment, which is used for the synthesis of sensitive substances, battery research, and drug development, etc.
Carrier gas (GC): One of the commonly used carrier gases in gas chromatography analysis.
Laser gas: The component of the working gas for certain ion lasers.

4.Other important areas:

Food preservation: Arsenic gas is filled into the packaging to displace oxygen and inhibit the growth of microorganisms, thereby extending the shelf life of food (such as wine, potato chips, etc.).
Medical applications: Argon plasma used for coagulation during surgery (argon ion beam coagulation); Cooling of MRI superconducting magnets.
Fire protection: Inert gas fire suppression systems for certain special occasions.

Safe operation and storage (of utmost importance!) ：

Asphyxiation risk: Major danger! Argon gas itself is non-toxic, but at high concentrations it will quickly displace the air, causing oxygen deficiency and asphyxiation.
Be sure to use it in an area with good ventilation.
It is strictly prohibited to enter enclosed spaces (such as storage tanks, pipelines, pits, etc.) where argon gas may accumulate. Before entering, the oxygen content (O2 > 19.5%) must be tested.
Install oxygen concentration alarm devices in the working area.
Pressure risk: High-pressure cylinders possess potential energy.
The gas cylinder must be upright and securely fixed to prevent any impact or fall.
Use a qualified pressure reducing valve and slowly open the valve.
Stay away from heat sources and fire sources, and avoid direct sunlight.
Low-temperature risk (liquid argon): Exposure to liquid argon can cause severe frostbite.
During operation, it is necessary to wear anti-freeze gloves, goggles/face masks and protective clothing.
Ensure proper ventilation to prevent the accumulation of oxygen which could lead to a fire hazard.
Leakage handling: In case of leakage, immediately shut off the gas source, enhance ventilation. Personnel should evacuate from the area with insufficient oxygen. Do not use open flames in the leakage area.
