Palladium is a chemical element with the symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal that belongs to the platinum group of elements. Palladium has a melting point of 1,554.9°C and a boiling point of 2,963°C, making it a valuable material for high-temperature applications. It is also highly resistant to corrosion and tarnishing, which makes it an excellent choice for use in jewelry, dental fillings, and other decorative applications. Palladium is commonly alloyed with other metals to improve its mechanical, electrical, or chemical properties. For example, palladium-silver alloys are used in electrical contacts and connectors due to their high conductivity and resistance to corrosion. Palladium-nickel alloys are used in hydrogen storage applications due to their ability to absorb and release hydrogen gas. Palladium-copper alloys are used in coinage due to their durability and resistance to tarnishing. One of the most important applications of palladium alloys is in the automotive industry, where they are used as catalysts in catalytic converters. These devices convert harmful pollutants in automobile exhaust gases into less harmful substances by catalyzing chemical reactions. Palladium is an effective catalyst for this purpose because it is able to promote the necessary chemical reactions at relatively low temperatures. In recent years, the demand for palladium has increased due to its use in electronic devices, such as smartphones and laptops. Palladium is used in these devices as a component of multilayer ceramic capacitors, which are essential for the operation of electronic circuits. As a result, the price of palladium has risen significantly, making it a valuable commodity for investors and traders.
