History of PGM

In the 18th century platinum was a tough challenge to European scientists trying to understand and use the metal. Their difficulties came from the very properties which make platinum suitable for so many applications, such as its high melting point and its great resistance to corrosion. The problems were compounded by the other metals of the platinum group, which were present in raw platinum ...
