Platinum has often been called
Rich Man’s Gold. Platinum is significantly more rare than gold and historically has usually been more expensive. In fact, over the past 40 years, the price of platinum has averaged about 1.5 times the price of gold.
Platinum (Pt) is a heavy, soft and ductile metal. It is defined as a “noble metal”, meaning that it is nonreactive to chemicals, non-corrosive, and its integrity is not compromised by acids.
Platinum is most useful for its catalytic properties: it speeds up chemical reactions without itself changing in the process. Platinum’s catalytic properties were first discovered by German chemist Johann Wolfgang Döbereiner (1780–1849).
