Platinum

Platinum is a silvery metallic chemical element, a member of the six transition elements in Group VIII of the periodic table known collectively as the platinum metals (ruthenium, rhodium, palladium, osmium, iridium, and platinum). Platinum has the symbol Pt, its atomic number is 78, and its atomic weight is 195.09.

The electronics industry uses platinum for computer hard disks and thermocouples. Platinum is also used to make optical fibres and LCDs, turbine blades, spark plugs, pacemakers and dental fillings. Platinum compounds are important chemotherapy drugs used to treat cancers. Platinum has no known biological role.

Identity.

History.

The history of platinum stretches back centuries, with early traces of its use found in ancient Egyptian and South American civilizations. However, it wasn't until the 18th century that European scientists began to understand its unique properties and separate it from other metals. The name "platinum" is derived from the Spanish word "platino", meaning "little silver," due to its resemblance to silver but with a higher weight.

Following its isolation, scientists and engineers began to explore the potential of platinum

Usage.

Excellent electrical conductivity: This property is valuable in various electronic applications.
Catalytic properties: Platinum can accelerate chemical reactions, making it essential in various industrial processes.
Jewelry: Platinum is a popular metal for jewelry due to its durability and lustrous shine..

Some of the benefits of using platinum are:

Platinum is highly resistant to corrosion and wear and tear, making it ideal for long-lasting products like jewelry, scientific instruments, and industrial equipment.
With a very high melting point, platinum can withstand extreme temperatures without melting or losing its shape. This makes it valuable for components in high-heat environments, such as aircraft engines and crucibles.
Platinum can act as a catalyst, accelerating chemical reactions without being consumed itself. This has numerous applications in various industries.

Sources.

platinum in quantity is limited to a few localities. 80% of the world's current production comes from South Africa and the Sudbury Basin of Canada. Smaller reserves can be found in the United States, Zimbabwe and Australia. Platinum is also attained through recycling.
