Tarix
Platinum was first used by pre-Columbian South American natives to produce artifacts.
Antonio de Ulloa published his findings about platinum in 1748, but Sir Charles Wood also investigated the metal in 1741.
First reference to it as a new metal was made by William Brownrigg in 1750.

Applications
The most common use of platinum is as a catalyst in chemical reactions.
Platinum is used in jewelry, decoration and dental work.
Platinum-cobalt, an alloy of roughly three parts platinum and one part cobalt, is used to make relatively strong permanent magnets.
Platinum-based anodes are used in ships, pipelines, and steel piers.
