Analysts attribute growing demand for platinum, as well as palladium, in part to tougher pollution-emission standards that are increasing demand for catalytic converters, which use one of the two metals to filter car exhaust. The auto industry has grown to account for 47 percent of all platinum used in just 30 years. Also used widely in jewelry, electronics as well as glass and chemical industries, platinum prices are driven primarily by supply-demand fundamentals because of its industrial nature
This is very true and is also one of the main reasons for the growing demand of the metal and also its increasing price. Platinum is more than just being a jewelry.
