Introduction to Palladium
Palladium (Palladium): element symbol Pd, is one of the platinum group elements. 1803 by the British chemist Walaston found in the separation of platinum. It is similar to platinum, with excellent characteristics, normal in the air will not oxidize and lose luster, is an unusual treasure of precious metals resources. Palladium watch case
Platinum-based metal-metal among the “noble house”
Palladium was a British chemist in 1803, and the physicist, Wollaston, first succeeded in separating from the coarse plutonium, and the palladium began to have its own name, Palladium. The name comes from the newly discovered solar asteroid Pallas-Athena in 1802. It is a memorial to the ancient Greek mythology of wisdom and craft goddess Athena planet.
Palladium, a member of the platinum group, the element symbol Pd, the appearance and platinum similar to the silver-white metallic luster, bright color. The proportion of 12, lighter than platinum, ductility strong. Melting point of 1555 ℃, hardness 4-4.5, slightly imitation Cartier love bracelet harder than platinum. Chemical properties are more stable, insoluble in organic acids, cold sulfuric acid or hydrochloric acid, but soluble in nitric acid and aqua regia, under normal state is not easy to oxidize and lose luster. The density of palladium is 1 co-cm of 12.023 g. Palladium watch case

Palladium is relatively stable, can acid corrosion. Palladium is almost no impurities, high purity. Palladium is also very suitable for pure skin, because with other metals containing impurities, palladium will not cause skin allergies, the international jewelry industry began processing palladium and platinum, as jewelry and decorative works of art, and gradually form a fashion trend. Palladium has excellent physical and chemical properties, high temperature, corrosion resistance, wear resistance and has a strong stretch, in purity, degree of durability and durability, can be replaced with platinum, regardless of whether the production of jewelry or Inlaid precious stones, called the ideal material.
Palladium jewelry is beautiful, from the ancient Greeks rich romantic fashion temperament and classical living mood, so that people get the beauty of the enjoyment. It is pure, beautiful, wisdom, eternal symbol. As a constituent of nature, palladium was separated from crude platinum by British chemical and physicist Voroston in 1803. Due to its nature and the similarity of Pt, palladium was initially used as an additive element for platinum jewelery. Until recently people will be the main elements of its production of jewelry.
The charm of palladium
Precious, pure, eternal!
Palladium is one of the world’s most rare precious metals, the crust in the content of about one hundred million, much more scarce than gold. The world only Russia and South Africa and a few countries, the total annual output of less than 5 ‰ of gold. Than platinum is also rare. Palladium unusually tough, made of palladium jewelry not only has a natural charm of platinum-like natural, but also withstand the tempered years, as long as new Palladium is almost no impurities, high purity, shining white light. The purity of palladium is also very suitable for the skin, will not cause skin allergies.
The difference between palladium and other white metals
Also known as K platinum, it is an alloy, is the gold and other white metal fusion made after. Its code WG (White Gold), that is, the meaning of white gold. White K gold jewelry commonly used “18K white gold” or “14K white gold” and so on.
Symbol Pt, silver gray, the proportion of 21.35, the melting point of 170 ° C, Mohs Replica Cartier jewelry hardness of 4-4.5 degrees, stable chemical properties, in addition to Wang Yu outside without acid and alkali corrosion. Pure platinum is relatively soft, adding ruthenium, rhodium, palladium and other metals will increase its hardness.
Refers to platinum and other metal alloys, such as with palladium, rhodium, yttrium, ruthenium, cobalt, copper and so on. Although pure platinum hardness than gold, but as a mosaic with the lack of, and other metal alloys must be used to make jewelry. International platinum jewelry markings are Pt, Plat or Platinum words, and the purity of thousands of points on behalf of, such as Pt900 that purity is 900 ‰. Commonly used platinum jewelry marked Pt1000, Pt950, Pt900, Pt850.
Platinum group of a member, silver white, symbol Pd, lighter than platinum, ductility stronger than platinum slightly hard, insoluble in organic acids, cold sulfuric acid or hydrochloric acid, but soluble in nitric acid and aqua regia. Normal is not easy to oxidize and lose luster. Jewelry industry used alone, or as gold, silver, platinum alloy composition, to increase its hardness. Market gold, palladium, gold and platinum, palladium alloy.
Palladium selection guide
International palladium jewelry stamps are “Pd” or “palladium” words, and the purity of thousands of representatives, such as Pd900 that purity is 900 ‰,
Palladium jewelry specifications are marked Pd1000, Pd950, Pd900, Pd850. After the purchase of jewelry, businesses issued invoices are marked “palladium platinum” or “pd” words.
Palladium jewelry maintenance
1, the first best to wear alone, so as not to wear each other.
2, jewelry items should be prevented from pulling, squeezing, collision, friction, do not wear should be a single item collection.
3, regular cleaning of palladium jewelry. This ensures that the jewelry exhibits the best www.ourlovestore.com luster and is more durable.
4, all precious metals are likely to leave scratches, palladium is no exception, if there are visible scratches, please palladium jewelry to repair qualified qualified jewelry store for polishing.
5, should try to avoid contact with bleach or irritating chemicals.
Other uses of palladium
Palladium and platinum in addition to making jewelry, but also mainly used for the production of automotive catalysts, electronic and dental medical equipment and so on. In recent years, the international not only the production of jewelry with palladium, but also to solve the production technology, but also the development of the palladium as the material of the expensive watch. Chopin, Cartier, Parma Johnny and other world’s top brand watches, has been the development of new palladium watches to the international luxury goods market, the price of each equivalent of several hundred thousand yuan or even millions of yuan.
