Since it is a catalyst, one of the most common uses of palladium is in catalytic converters for cars and other vehicles. Palladium is also commonly present in dental and surgical equipment, jewelry and various electronics.
Though palladium is not generally a well-known element, it plays important roles in many everyday objects. Metallurgists often mix this corrosion-resistant metal with other metals to create alloys such as white gold. It is also commonly present in ceramic capacitors that regulate DC voltage flow in computers, phones, cameras and other electronic devices. Another slightly less common use for palladium is in the purification of hydrogen gas.
