Palladium Metal (Pd)-Pellets

Palladium Metal (Pd)-Pellets introduce:

Characteristic




Palladium is a chemical element with the symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal.They have similar chemical properties, but palladium has the lowest melting point and is the least dense of them.

Melting point： 1828.05 K (1554.9 °C, 2830.82 °F)

Boiling point： 3236 K (2963 °C, 5365 °F)

Density (near r.t.)： 12.023 g/cm3

when liquid (at m.p.)： 10.38 g/cm3

Heat of fusion： 16.74 kJ/mol

Heat of vaporization： 358 kJ/mol

Molar heat capacity： 25.98 J/(mol·K)




Application




More than half the supply of palladium and its congener platinum is used in catalytic converters, which convert as much as 90% of the harmful gases in automobile exhaust (hydrocarbons, carbon monoxide, and nitrogen dioxide) into less noxious substances (nitrogen, carbon dioxide and water vapor). Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and jewelry. Palladium is a key component of fuel cells, which react hydrogen with oxygen to produce electricity, heat, and water.
