When you hear the word ‘argon’, it doesn’t spring to mind as quickly as hydrogen or helium.<\/p>\n\n\n\n

The nature is also moderately difficult to remember…<\/p>\n\n\n\n

However, knowing what it is used for in society and why argon is used can help you remember its properties. Let’s look at this element together, as it is widely used in ordinary households and in the medical field, and is surprisingly familiar to us!<\/p>\n\n\n\n

Properties and characteristics of Argon<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

It has the property of being stable and not causing chemical reactions. 1% in air and is cheaper to obtain than other inert gases. This element is mainly used in laboratories, such as universities.<\/p>\n\n\n\n

How Argon is used in society<\/h2>\n\n\n\n

Argon is used as a component of ‘medical lasers’, ‘sputtering equipment’ and ‘fluorescent lamp contents’.<\/p>\n\n\n\n

Let’s look at each of them.<\/p>\n\n\n\n

Argon is useful for \u201cMedical laser (retinal treatment)\u201d<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

This laser is often used in ophthalmology and is performed as a surgical procedure to reduce the progression of retinal disease. Various elements are used in medical lasers, but the ‘argon laser’, which uses argon ions, is used in the treatment of retina.<\/p>\n\n\n\n

The argon laser is used by many ophthalmologists because it is less easily absorbed by water and more easily absorbed by red (blood), resulting in less strain on the eye and faster recovery.<\/p>\n\n\n\n

Argon is useful for \u201csputtering equipment\u201d<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Argon is also used in sputtering equipment for film deposition.<\/p>\n\n\n\n

This makes use of the fact that argon is stable and does not cause chemical reactions. The use of stable argon makes it possible to deposit copper as copper and iron as iron. (There is also a technique called reactive sputtering, in which argon is mixed with a little oxygen or nitrogen for sputter deposition.)<\/p>\n\n\n\n

Here are some examples of sputtering equipment.<\/p>\n\n\n\nList of sputtering equipment<\/a>\n\n\n\n

Argon is useful \u201ccontents of fluorescent lamps\u201d<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Two types of gas are enclosed in fluorescent lamps: mercury gas and argon gas. Argon gas is mainly put in to keep the discharge constant.<\/p>\n\n\n\n

Incidentally, let’s talk about why fluorescent bulbs glow.<\/p>\n\n\n\n

The flow of electricity causes collisions between electrons and mercury atoms, which emit ultraviolet radiation. This ultraviolet radiation hits the phosphor coated on the surface of the fluorescent lamp, which illuminates it brightly.<\/p>\n\n\n\n

History of Argon<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Chemical symbol: Ar
English Name: Argon<\/p>\n\n\n\n

The word argon is derived from the Greek word ‘aergon’, meaning ‘that which does not work’. As for the discovery, Ramsey and Reilly found it in the air in 1984.<\/p>\n\n\n\n
