Definition of palladium

Palladium, a member of platinum group, is similar to platinum in appearance, with silver white metallic luster and bright color. Specific gravity 12, lighter than platinum, strong ductility. The melting point is 1555 ℃, and the hardness is 4-4.5, which is slightly harder than platinum. It is not soluble in organic acid, cold sulfuric acid or hydrochloric acid, but soluble in nitric acid and aqua regia. It is not easy to oxidize and lose luster under normal conditions.

Palladium is one of the rarest precious metals in the world. Only a few countries such as Russia and South Africa produce palladium, and the total annual output is less than 8% of gold. Norilsk Nickel, the world's largest producer of nickel and palladium, increased platinum production to 186000 ounces in the second quarter of 2012 from 166000 ounces in the first quarter of 2012, while palladium production increased from 649000 ounces to 729000 ounces.

Although the international price of palladium is cheaper than that of platinum, in history, the international price of palladium was about 100 yuan / g higher than that of platinum (the international price of palladium was as high as 1094 US dollars / ounce on January 26, 2001). Palladium, rhodium, iridium, platinum and other metals are smelted from PGE minerals.

Palladium is a member of the platinum group, but it is different from platinum: first, palladium's component seal is "PD", while platinum's component seal is "PT"; second, palladium's density is lower than platinum, the same cubic centimeter, platinum weighs 21.45g, while palladium weighs 12.023g, only 56% of the former, which means that for ornaments of the same size, palladium's weight is only a little more than half of platinum (placed in the The price of palladium is lower than that of platinum.

Advantages of palladium

Palladium is stable and resistant to acid attack. Palladium is almost free of impurities and of high purity. The purity of palladium is also very suitable for the skin, because unlike other metals containing impurities, palladium will not cause skin allergic reaction. The international jewelry industry began to process palladium platinum to make it used as jewelry and decorative art, and gradually formed a fashion trend. Palladium has excellent physical and chemical properties, high temperature resistance, corrosion resistance, wear resistance and strong extensibility. In terms of purity, rarity and durability, palladium can replace platinum. Whether it is used to make jewelry alone or inlaid with gems, palladium can be regarded as the most ideal material.

The beauty of palladium jewelry originates from the romantic and fashionable temperament and classical life sentiment of ancient Greeks, which makes people enjoy beauty. It is a symbol of purity, beauty, wisdom and eternity. Palladium, as a component of nature, was separated from crude platinum by Wallaston in 1803. Due to the similarity of its properties with Pt, palladium was initially used as an additive element in platinum jewelry.

Which is more expensive, palladium or platinum

Which is more expensive, palladium or platinum? Platinum is expensive, at least twice as much. Palladium and platinum are precious metals for making jewelry. Both of them are very similar in appearance, but in price, palladium is only half the price of platinum, even cheaper. Therefore, in order to save money, many people will choose palladium jewelry.

Palladium, the element symbol PD, is one of the platinum group elements. Similar to platinum, it has excellent properties and will not oxidize and lose luster in the air under normal conditions. It is an extremely rare precious metal resource. Silver white metallic luster, bright color. Specific gravity 12, lighter than platinum, strong ductility. The melting point is 1555 ℃, and the hardness is 4-4.5, which is slightly harder than platinum.

Platinum (PT for short) is a kind of natural white precious metal. According to the national regulations, only jewelry with platinum content of 85% or more can be called platinum jewelry, and it must have Pt mark.
