The word ‘titanium’ sounds familiar.<\/p>\n\n\n\n

But what are its properties and how is it used in familiar objects? This is one of the elements that is difficult to answer for such questions.<\/p>\n\n\n\n

This article will explain titanium.<\/p>\n\n\n\n

This section also introduces the properties of titanium, how it is used in society, the etymology of the word and who discovered it.<\/p>\n\n\n\n

This element has interesting properties, so let’s learn about them together.<\/p>\n\n\n\n

<\/div>\n\n\n\n

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

Titanium is a light and hard element.<\/p>\n\n\n\n

It is tough enough to withstand high temperatures and is rust resistant.<\/p>\n\n\n\n

On the other hand, there are drawbacks such as high prices and difficulties in processing.<\/p>\n\n\n\n

It also has the property of forming a thin oxide film on the surface, which prevents rust from progressing to the interior and, thanks to this film, is less likely to cause metal allergies.<\/p>\n\n\n\n

In nature, it is abundant in rocks and exists in the form of ‘ rutile ‘ and ‘ sphene ‘.<\/p>\n\n\n\n

Incidentally, the ‘moon rock’ brought back by Apollo 11 contained a few per cent titanium.<\/p>\n\n\n\n

Let’s look at how they are used in society, one by one.<\/p>\n\n\n\n

How Titanium is used in society.<\/h2>\n\n\n\n

Titanium is used as an ingredient in ‘shape memory alloys’, ‘dental implants’ and ‘white pigments’.<\/p>\n\n\n\n

Let\u2019s look at each of them.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Titanium is useful \u201cshape memory alloy\u201d<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Alloys combining titanium and nickel are used as shape memory alloys, as they have the property of returning to their original shape after deformation.<\/p>\n\n\n\n

Recently, shape memory alloys have been used for eyeglass frames.<\/p>\n\n\n\n

Incidentally, old mobile phones had extendable antennas and the antenna material was also a shape memory alloy.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Titanium is useful \u201cdental implant\u201d<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Implant treatment, which has attracted a lot of attention in recent years, is one of the treatments for missing teeth, and the body of the implant used in the treatment is made of titanium.<\/p>\n\n\n\n

The implant is placed in the jaw bone, and titanium actually bonds easily to the bone and integrates with it.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Titanium is useful \u201cWhite pigments\u201d<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

White pigments (water-insoluble paints) are mainly composed of titanium dioxide.<\/p>\n\n\n\n

Commonly known as ‘titanium white amber’.<\/p>\n\n\n\n

It is not easily affected by light, heat or chemicals, and is non-toxic, making it easy to use for many things.<\/p>\n\n\n\n

<\/div>\n\n\n\n

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

Chemical symbol; Ti<\/p>\n\n\n\n

The word titanium is derived from the Greek mythological giant ‘Titan’.<\/p>\n\n\n\n

The Titans, defeated in battle against the Olympian gods, were imprisoned beneath the earth. From this myth, the element trapped within ore was named \u201ctitanium.\u201d<\/p>\n\n\n\n

As for its discovery, Gregor discovered it and the German scientist Klapprodt announced that it was a unique oxide, which was then named ‘titanium’.<\/p>\n\n\n\n

Summary<\/h2>\n\n\n\n

In this article, we have explained ‘titanium’.<\/p>\n\n\n\n

The key points of this article are as follows.<\/p>\n\n\n\n

Titanium is light, hard and rust-resistant.<\/p>\n\n\n\n

Used in \u2018shape memory alloys\u2019, \u2018dental implants\u2019 and \u2018white pigments\u2019.<\/p>\n\n\n\n

The other elements studied in high school are summarized in the following articles.<\/p>\n\n\n\n
