Silver is an important catalyst in the production of two major industrial chemicals. More than 150 million ounces of Silver is used to produce ethylene oxide and formaldehyde, both essential ingredients in plastics.
A catalyst is a substance that facilitates a chemical process without itself undergoing any transformation. Because Silver is not affected by the reaction, it is almost completely recovered after it is used.
Approximately 90% of the Silver employed as an industrial catalyst is used for the production of ethylene oxide, from ethylene.
