Argon is odourless, colourless and monoatomic inert gas heavier than air. It is almost insoluble in water. Argon is non-toxic, but as nitrogen it may displace oxygen from air. Since argon is heavier than air, it may accumulate near the ground surface, especially in cavities. At high pressure, argon changes the state of ideal gas. For example, at pressure of 200 bar, a gas cylinder contains approximately by 7 % more argon compared to the case when ideal gas is used.
Air contains 0.934 % by volume, whereas lithosphere contains 4·10-60; argon makes the greatest part of inert gas in atmosphere. At 0°C and 101.325 kPa, density of argon is 1.784 g/l, whereas the melting point is -189.35°C, boiling point is -185.85°C, triple point is -189°C at 69 kPa and critical point is -122.28°C (at 4.898 MPa).
Argon is obtained from the atmospheric air by means of deep freezing and is filled into grey cylinders with dark green shoulder, Euro cylinders and other cryogenic tanks.
Argon is used for creating an inert medium, in chemical synthesis and nuclear mechanics, in metallurgic and metal processing processes, for production of semiconductor materials and glass units, for production of advertising lamps (glowing in blue), for filling air bags of motor vehicles.
Gaschema offers you technical argon by 40 l (6.4 m3, 150 bar) and 50 l (10.7 m3, 200 bar).
