Question

Why is Titanium metal called a strategic metal? Mention two of its properties which makes it too special.

Answer 1

Hint:Titanium is a transition metal light with a white-silvery-metallic colour. Titanium is called strategic metal because it is used for making certain war equipment.

Complete answer:
Titanium is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver colour, low density, and high strength.
A strategic metal is basically a metal that is important for significant industries of a country such as energy, aerospace, telecommunication, computer, mobile technology and national defence of the country. These industries play an important role in the strategic and economic development of a country. Let us look at some properties of a strategic metal, they are:
Strategic metal should be light in weight but at the same time it should be stronger than other metals.
Strategic metal should not be affected by corrosion (should not be affected by moisture, air, water etc.) even if it is kept for a very long time.
Now, let us look at some of the properties of Titanium which make the metal so special, they are:
-It is light in weight but at the same time stronger than the other metals.
-It is not affected by corrosion even if kept in the open for a very long time.
-This is why Titanium is called a strategic metal. It’s two properties, which make it a strategic metal are listed above.

Note:
Titanium is as strong as steel but much less dense. It is therefore important as an alloying agent with many metals including aluminium, molybdenum and iron. The largest use of titanium is in the form of titanium(IV) oxide. It is extensively used as a pigment in house paint, artists’ paint, plastics, enamels and paper.
