A rare metallic element of the light platinum group, found native, and also alloyed with platinum and gold. It is a silver-white metal resembling platinum, and like it permanent and untarnished in the air, but is more easily fusible, with a melting point of 1555° C. It can also be prepared as a finely divided black powder. It is unique in its power of absorbing hydrogen, which it does to the extent of nearly a thousand volumes, forming the alloy Pd2H. It is used for graduated circles and verniers, for plating certain silver goods, and somewhat in dentistry. It was so named in 1804 by Wollaston from the asteroid Pallas, which was discovered in 1802. Symbol Pd. Atomic number, 46. Atomic weight, 106.42. Density 12.0.
A silvery-white metal. Atomic Number 46 Chemical Symbol "Pd". Melting point 1552oC Most often used as a constituent of white gold.
A white metallic element, used in dentistry, jewelry, and chemical and electrical equipment. Used to make white gold, without causing the stress corrosion that can happen in nickel alloys.
a silver-white metallic element of the platinum group that resembles platinum; occurs in some copper and nickel ores; does not tarnish at ordinary temperatures and is used (alloyed with gold) in jewelry
is a non-tarnishing precious metal that is often used as an alternative for rhodium, although it is not as white. Palladium is also used as a barrier coat in the nickel-free process.
metal (Pd) used to make electrical connectors and small tools that need to be very exact such as watches or tools used in hospital operations; Palladium is also used in jewellery. 34
A brilliant silver-white precious metal.
Is related to platinum but is less dense and has a lower melting point. At one time it was very popular in jewelry making but now days the cost per ounce means it is not used as much
Palladium is a noble metal with the chemical symbol "Pd". It is in a comparable silver manner and it was used to produce nibs for fountain pens.
A charcoal gray form of platinum found in Russia, South Africa and North America. Palladium has many of the same properties as platinum such as its resistance to corrosion and versatile applications in jewelry designs. Pieces made with Palladium bear the hallmarks of Pd950 or Pd500.
CAS Number: 7440-05-3. A moldable, silver-white metal used extensively in industry as an alloy with gold, silver and copper. Chemical formula = Pd. Molecular weight = 106.40 g/mol.
Important jewellery metal, used in high quality alloys of platinum and white gold.
An iron (non-silver) process for making photographic prints in which palladium is reduced from a salt to form the image. Introduced around 1916 when platinum became very expensive because of World War I. This process is still widely used today.
A plating that gives an excellent hard "white grey" finish that is often mistaken for "white gold". It has high tarnish resistance making it an ideal plating for both jewellery and leathergoods hardware.
This is a charcoal gray form of platinum which is endemic in North America, South Africa and Russia. It has similar properties as platinum such as corrosive– resistant and versatile application in jewelry design. However, it is less dense than platinum.
Palladium is a valuable, durable, and malleable light-gray metal used in some jewelry; it is related to platinum, but is less dense and has a lower melting point. Unlike platinum, palladium reacts when exposed to aqua regia, sulfuric, nitric, and hydrochloric acids. It also develops a tarnish when it is heated. Pallasium is not a shiny as platinum. Palladium was only isolated as an element in 1802 by William Hyde Wollaston and Smithson Tennant. It was first used in jewelry in 1939 (during World War 2, platinum was used for war purposes, and was not available for jewelry making - palladium was temporarily used as a substitute for platinum). White gold is sometimes alloyed with palladium (instead of nickel), resulting in a gray-white gold. After World War 2, palladium was rarely used in jewelry making beacuse of some difficulties in working with it. Palladium was recently discovered to be useful in engine catalytic converters, and its price skyrocketed to over $700 per ounce (it had previously been much less expensive than platinum or gold) and is no longer practical to use as jewelry.
A photographic process in which the image is produced by palladium crystals deposited on the paper. A steel-white and tarnish-resistant metallic element used in jewelry, watches and surgical equipment. Also called white gold.
Palladium (IPA: ) is a chemical element with symbol Pd and atomic number 46. A rare silver-white transition metal of the platinum group, palladium resembles platinum chemically and is extracted from some copper and nickel ores. It is primarily used as an industrial catalyst and in jewelry.
