Platinum

Platinum Element:

The chemical element Platinum is a lustrous silvery-white, malleable, ductile transition metal. Platinum is member of platinum group of element along with iridium, rhodium, osmium, Palladium and ruthenium. Its atomic number is 78 and represented by the symbol Pt. In the Periodic table of elements it is a d-block metal and it belong to the 10th group and 6th period. It is one of the rare elements in the Earth’s crust. Pt is found uncombined in alluvial deposits and as alloy with the other platinum-group metals. Commercially it is produced from the mineral cooperate and also produced as a by-product of copper-nickel refining. Platinum is highly valuable and is a major precious metal commodity. Pt contains six naturally occurring isotopes such as 190Pt, 192Pt, 194Pt, 195Pt, 196Pt and 198Pt.

Uses Of Platinum Element:

  • Platinum is used to make jewellery, dental fillings, optical fibres, LCDs, turbine blades, spark plugs and pacemakers.
  • It is used in catalytic converters for cars, trucks and buses.
  • In the chemicals industry, Platinum is used as catalyst for the production of nitric acid, silicone and benzene and to improve the efficiency of fuel cells.
  • Pt is used in the electronics industry for computer hard disks and thermocouples.
  • Pt compounds such as cisplatin, oxaliplatin and carboplatin are important chemotherapy drugs used to treat cancers.
