WHAT IS THE ARGON GAS UDED FOR?

Question

What are the characteristics of argon gas and where is this gas used and what are the applications? is that dagerous?

Answer 1

Argon gas is a colorless, odorless, inert, nonflammable gas that is used in making florescent light bulbs.

Answer 2

Argon, being almost completely inert (non-reactive), is used in incandescent light bulbs to prevent the filament from reacting with oxygen.

It has other uses, but this is a common one.

Answer 3

Argon gas is a noble gas with an atomic mass of approximately 40 g/mol. Argon makes up about 1 % of the gas in our air. As a result, it is distilled from the air for use in industry and science. Argon is not inherently dangerous, unless it displaces (replaces) all the oxygen in a closed environment. In this case, one could suffocate. The same is true for nitrogen. But, argon is completely inert and therefore very safe if used with proper ventilation and proper volumes.

In industry argon gas is used to fill incandescent bulbs or used in fluorescent lighting mixed with volatile compounds/elements such as mercury. Also, some hollow cathode lamps are argon filled. Argon is also used for welding in MIG and TIG applications. In welding, it just acts as an inert insulating layer. In many application anaerobic environments or inert environments are needed in industry. Silicon wafer production, drug preparations, and anti-oxidative environment applications. It's used to fill double pane windows to increase R-value. There are even more uses such as for extinguishing fires.

In science, argon gas is used, because it is relatively cheap, to dry samples and perform analyses in anaerobic environments--Nitrogen is often used for the same means. Also, some samples are stored under argon if they are easily oxidized. Argon is also used for inductively coupled plasma spectroscopy/spectrometry. Also, argon is used in microwave plasma and direct current plasma operations. Because of the relatively high first ionization potential (~15 eV) of argon, it is useful in these applications for the production of excited state atoms and ions from molecular samples. This makes argon plasmas very useful in optical and mass spectrometric analyses. Some of these argon plasmas are as hot as 10,000 K. Also, ionized argon is used for atomic sputtering. Argon is used in pneumatic nebulization as well for many forms of atomic spectroscopy. Argon is used to produce blue argon lasers.

Hope this helps, I use this stuff every day in my ICP-MS lab!

Answer 4

light bulbs. dual pain windows, fire suppression systems, ballistic missile thrust control systems, silicon wafer manufacture to name a few

used in thermal imaging to insulate the heat from the user so it dosen't effect the image

Answer 5

they fill incandescent light bulbs with it.

Answer 6

light bulbs
