wholesale women's jewelry (PD) One of the platinum metals is also one of the precious metals commonly used in jewelry. It belongs to the platinum metal metal with platinum (PT), and it has high reflectivity of visible light. n (The above color refers to the highly higher platinum and tadpoles, and most of the finished jewelry products are alloys, and the color is different.) For PT, at least 50%of platinum must be contained, and a total of 95%of platinum metals. Platinum content, which is higher than 95%, can be put on PT mark. Jewelry with platinum content between 75%-95%must also be marked with platinum metal. Jewelry with platinum content between 50%-75%must be put on the name and content of the platinum metal metal.
The physical and chemical properties are also very close:
platinum (PT) --- At room temperature, acid-resistant and chloride corrosion can be slowly corrosive. It can only be corroded when adding oxidants. Platinum can also corrode platinum at room temperature. Halogen can corrode platinum at high temperatures. The melted potassium cyanide (sodium) can strongly corrode platinum. Platinum water and sulfuric acid with boiling king water.
The platinum (钯) adsorbing organic steam. Carbon and carbides affects physical and mechanical properties. Therefore, when manufacturing and using platinum, 钯 and alloys, you should avoid contact with this internal material.
钯 (PD) --- corrosion, the surface is not dull at room temperature. Hydrofluoric acid, perchloric acid, phosphate, and acetic acid are not corroded at temperature, but hydrochloric acid, sulfuric acid, and hydride can be slightly corroded. Nitric acid, iron chloride, hypochlorite and wet halogen can quickly corrode.
The platinum color is pure white, and the reserves of platinum in nature than gold are scarce, so the price is more expensive than gold. Platinum can keep white diamonds maintaining the original color and firmness. It is the best material inlaid with diamonds. It is a superstar for diamonds to make platinums as precious metals. Most of the inlaid inlaid in my country is PT950 and PT900, and PT900 is the most commonly used.
The regulations on the content of platinum jewelery in the "Pure and Naming Methods of Jewelry and Precious Metals and Metals", the total content of platinum and 钯 must not be less than 950%0. Platinum jewelry is crowned with platinum or PT with a purity of thousands. Example: 990, PT990 or Foot Platinum.

body jewelry chains wholesale 1. PD means golden gold, 999 is the purity of gold, and PD999 is a gold with a gold content of 99.9%. 2, 是 is a precious metal that is very similar to platinum, but it is cheaper than platinum in terms of price, so making jewelry is also very popular! But Jin Jin has a weak point, that is, it is easy to break, so pay more attention in protection! 3, in fact, Qianzu is just a name for merchants in the market, because the gold is not as popular as platinum, so that there are corresponding rules, it is divided into foot platinum and thousand -foot platinum. The current prices of Jinjin are the same. Whether it is the so -called footprint or a thousand feet, it is not too much. 4, 1 was first separated from the rough platinum in 1803 British chemists and physicists Vallaston, so I started to have their own name Palladium. The name comes from the newly discovered Sun-inrada, the newly discovered in 1802. It was the planet in commemorating the goddess of wisdom and craftsmanship in ancient Greek mythology. 5. The poke of the international gold jewelry is "PD" or "Palladium", which is represented by a purity thousands of numbers.
