The term platinum is derived from the Spanish term platina (“little silver” in English).
Platinum is one of the most rare precious metals in the Earth’s crust, typically found in only 5 μg/kg. Only a few hundred tonnes are produced annually.
Platinum is generally non-reactive, and has a high resistance to corrosion, leading it to be categorized as a noble metal.
Platinum is typically found in a pure state in the alluvial sands of rivers.
Platinum is used in catalytic converters, lab equipment, electronics, thermometers, jewelry, and dentistry equipment.
