Appreciation of Platinum Products (18)
Platinum jewelry is not pure. The purity of platinum jewelry is usually as high as 90%-95%. Look at the purity of platinum jewelry Pt900Pt950 According to family regulations, only when the platinum content reaches 850‰ can jewelry be called platinum jewelry. Platinum jewelry is extremely pure, which makes the skin sensitive. Platinum white luster is pure, giving platinum jewelry a unique appearance, even if it is always pure and flawless.
dilute
Platinum is 30 times thinner than gold. Only a few people in the world use platinum from all over the world and pour it into the Olympic standard swimming pool. Deep enough to cover the instep. At least three swimming pools are full of gold. 3 grams is just the weight of a platinum ring. It takes about 8 weeks to extract some platinum.

The symbol Pd, a member of palladium platinum group, is similar to platinum in appearance, with silvery metallic luster and bright color. Its specific gravity is lighter than the ductility of platinum 12 and its strong melting point is 1555℃. Its hardness is 4-4.5, which is slightly more stable than platinum. Organic acids, cold sulfuric acid or hydrochloric acid dissolved in aqua regia nitrate are easily oxidized and discolored.
Palladium: element symbol Pd platinum group element 1803 was changed from English to Chinese.
porpezite
A rare precious metal resource with excellent characteristics similar to platinum was found in wollaston.
Mineral-like platinum group minerals belong to platinum subgroup, including iridium, rhodium, palladium and platinum, which are widely distributed in elemental minerals. A series of isomorphic mixed crystals are smelted from platinum group minerals, such as palladium, rhodium, iridium and platinum.
Platinum metal-metal noble family
Palladium 1803 wollaston, a British scientist and physicist, made great contributions to crude platinum at the earliest, and began to own palladium, whose name originated from 1802. The newly discovered sun planet pallas-Athena commemorates Athena, the ancient Greek god of wisdom and technology.
The density of palladium is 1 cm3, and the gram state of 12.023 is easily oxidized and discolored. The surface oxidation temperature rises to 900℃ to restore luster. Palladium is cheaper than platinum. Jewelry industry uses it alone or adds some ruthenium as part of gold, silver and platinum alloys to increase its hardness. See the specifications of gold, palladium, gold and platinum-palladium alloys Pd 1000, Pd950 and PD 9000 on the market.

Close to 8% of the total gold production (data source: platinum and palladium in 2009), palladium and platinum, gold and silver are traded in spot and futures, and the price of palladium is higher than platinum in history. With the increase of market demand, its value is gradually reflected.
