The palladium wire in our shop is made from palladium powder with purity greater than 99.95%. After vacuum melting, drawing process and polishing, pure palladium Pd > 99.95% (in fact XRF can be measured over 9999 9995 for conservative estimation), the diameter of the wire is 0.6mm, and the surface is bright and clean. (attention is 0.6mm!) [attention] (1) the palladium wire is sold for 10 centimeters, and is suitable for family experiments. The price tag is 10 centimeters, and the purchase of a unit is 10 centimeters. If you need 20 centimeters of products, please buy 2 units of products, others and so on. Because palladium wire is difficult to cut out the right weight according to weight, it is easy to cause unfair, so the store is sold by length, the price is also calculated, want to know the price of the buyer, the average weight of about 0.0365g per centimeter, diameter 0.6mm deviation, the price is a little selling price, stock allowance slight error exists Please pay attention to the above points by the demanding buyers. 3. The palladium wire, non plating, non hollow, solid palladium, is a custom pure palladium, for the compact state, basically equal to the theoretical density, ask this question buyer, unified reply. It can be used as a conductor that will not be oxidized. It can be used in the electronics industry, and it can also be used to make palladium mesh, and play a catalytic role in some chemical reactions. As the wire is used more flexibly, it can also be used as a chemical reagent to prepare palladium alloys and palladium compounds. It can also be used as palladium electrode for electrochemical experiments. Palladium (Palladium): element symbol Pd is one of the platinum group elements. It was discovered in 1803 by British chemist Wollaston in the separation of platinum. Palladium has a melting point of 1555 degrees. Palladium is not active in chemical properties. Palladium will not be oxidized in the air. It can remain shining permanently. Palladium has strong corrosion resistance. It can resist all organic acids, concentrated hydrochloric acid, cold concentrated sulfuric acid, and various kinds of dilute acids, but can dissolve in hot concentrated sulfuric acid, concentrated nitric acid and royal water. Precious metals have high chemical inertness, although palladium Pd and silver Ag are the two most active elements, but their stability and corrosion resistance are still far higher than those of other ordinary metals. It is similar to platinum. Under normal conditions, it will not oxidize or lose its luster in the air. It is a rare resource. In mineral classification, platinum group element minerals belong to the natural platinum subgroup, including natural elements of iridium, rhodium, palladium and platinum. The phenomenon of isomorphism replacement exists widely among them, and palladium is symbiotic with other platinum metals. Platinum metals - "noble house" in metal. The density of the palladium gold is 1 cubic centimeters, 12.023 grams, no oxidation and loss of luster in the normal state. The surface will produce oxide at the temperature of about 400 degrees C, but the temperature rises to 900 degrees C, and the gloss will be restored. Palladium is one of the rare precious metals in the world. In 2008, the world's total output of palladium was similar to that of platinum, less than 8% of the total output of gold. (data source: platinum palladium yearbook of 2009) palladium and platinum, gold and silver are the trading varieties of international precious metal spot and futures, and in history were once higher than platinum prices. Palladium is a non renewable scarce resource. With the continuous exploitation and market demand, its future value will be gradually reflected. ?
