In found process editing In 1803, British chemist Wrason discovered from a platinum ore again. A new element. He dissolved the natural platinum ore in the king water. After removing acid, he dripped the cyanide (HG (CN) 2) solution and obtained yellow precipitation. The sulfur, borax and this sediment together to obtain a shiny metal particles. He calls it Palladium (钯) and the element symbol is determined to be PD. The word came from the asteroid Pallas discovered at the time, from the goddess of wisdom of Greek mythology Ballas Pallas. The important steps of Wulaston's discovery is to choose mercury.尽管氰化汞溶液中几乎不含有氰离子(CN-)，但是当钯的离子(Pd )与它相遇时，却立即生成淡黄色的氰化钯(Pd(CN)2)沉淀，而其他铂The element does not form this cyanide precipitation. [1]
The difference is edit Platquinity Platinum usually refers to platinum in people's spoken language, but bad merchants maliciously confuse the concept. Many white metals are called platinum.
The white gold (White Gold) , also known as K platinum, it is a alloy that is made after melting gold and other white metals. Its code WG (White Gold), which means white gold. White K gold jewelry is often expressed in "18K platinum" or "14K platinum". In essence, it is 18K gold, but the color is white.
platinum (platinum) symbol PT, silver gray white, a proportion of 21.35, melting point 1769 ° C, Mo's hardness 4-4.5 degrees, stable chemical properties, except for king water, not except the king water Corrossed by acid and alkali. Pure platinum is relatively soft, and adding metals such as 钌, 铑, and 钯 will increase its hardness. Platin and golden gold are two of the smallest minerals in the platinum. The metallurgical properties of these two types are quite similar. Because they are equally rare and similar, they often make alternatives in various applications. There are only four varieties of gold, platinum, gold, and silver in the international precious metal spot and futures trading market.
The platinum alloy (Platinum AlLoy) The alloy of platinum and other metals, such as 钯, 铑, 钇, 钌, cobalt, copper, etc. Although pure platinum hardness is higher than gold, it is still inadequate as inlaid, and it must be used to make jewelry with other metal alloys. The label of platinum jewelry internationally is PT, PLAT or Platinum, and represented by a thousand points of purity. For example, PT900 means that the purity is 900 ‰. Common platinum jewelry is marked with PT1000, PT950, PT900, PT850. According to the international regulations, the platinum content cannot be called a jewelry than the PT900, and it can only be called a platinum alloy.
