Platinum

18 · Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name is derived from the Spanish term platino, meaning "little silver".[3][4] Platinum is a member of the platinum group of elements and group 10 of the periodic table of ...

Platinum group metals are also components of many autocatalysts, converting car exhaust gases in to less harmful substance. And our fascination with platinum as a rare and robust metal continues. The term 'platinum blond' came about in the 1930's when actresses with platinum jewellery were the stars of newly invented talking pictures.

WebElements Periodic Table » Platinum » the essentials

Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM). Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile. It has a coefficient of expansion almost equal to that of soda-lime-silica glass, and is therefore used to make ...

What Are Platinum Group Metals (PGMs)?

The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically, and anatomically similar. The PGMs are the densest known metal elements. Exceptionally rare, the six metals naturally occur in the same ore bodies. They are highly durable and, due to their high value, often recycled, giving them long life cycles.

The Biggest Platinum Metal Producers

Much like platinum ores in the Earth's crust, though, the production of platinum metal is highly concentrated, with the four largest refiners accounting for 67% of total platinum production. The world's largest platinum producer, Anglo Platinum, accounted for nearly 40% of all primary refined platinum and roughly 30% of total global production.
