Very Rare

Platinum is a very rare and valuable metal.

South Africa is the largest producer of platinum and is followed by Russia.

It is believed that South American people discovered platinum well before the arrival of Europeans.

They used a gold-platinum alloy for making ornaments and jewelry.

Platinum is not abundantly found in the earth’s crust and that is why a very small amount is produced every year.

The average abundance of platinum in the earth’s crust is 5µg/kg.

It has a melting point of 1768°C and a boiling point of 3825°C.

The name platinum is derived from the Spanish term ‘platina’ which means ‘little silver’.

A group of six elements including platinum in the periodic table is called the ‘platinum group’.

Corrosion Resistant

Platinum is the least reactive metal and is highly corrosion-resistant.

It is shiny and silvery-white in color.

Platinum is very ductile and malleable.

It is very dense and also has a very high melting point.

While platinum is more ductile than gold, it is not as malleable as gold.

It does not dissolve it Hydrochloric acid and Nitric acid but dissolves in Aqua Regia.

Platinum’s excellent corrosion resistant properties make it a very desirable metal for jewelry.

It has stable properties even at high temperatures.

What is Platinum  used for

Platinum is a rare element and is used for making jewelry, watches, and other ornaments.

However, the largest application of platinum is in the manufacture of a catalytic converter in the Vehicular Emission Control devices.

According to estimates, nearly half (46%) of total platinum produced is used for this purpose.

The second-largest use of platinum is in the jewelry manufacture (30%).

Other uses include oxygen sensors, spark plugs, anti-cancer drugs, and electrodes.

It is also used for making super-strong alloys, in dental work and medical instruments.
