Palladium, a member of the platinum group, element symbol Pd, is similar to platinum in appearance and has a bright silvery metallic luster. Specific gravity 12, lighter than platinum, ductility. Melting point is 1554℃, hardness 4-4.5, slightly harder than platinum. Chemical properties more stable, insoluble in organic acid, cold sulfuric acid or hydrochloric acid, but soluble in nitric acid and aqua regia. It is not easy to oxidize and tarnish under normal conditions. Palladium is a member of the platinum group of metals. Platinum metals include ruthenium, rhodium, palladium, platinum and so on. Most of them are more expensive than gold, and are typical of "noble homes" in metals.

Palladium has few reserves on earth, and it is difficult to extract and smelt palladium. Palladium is an indispensable key material in aerospace, aviation, navigation, weapons, nuclear energy and other high-tech fields as well as automobile manufacturing industry, and it is also an important investment variety in the international precious metal investment market.

Palladium has excellent physical and chemical properties, high temperature resistance, corrosion resistance, wear resistance and strong extension, and can be replaced with platinum and gold in purity, rarity and durability. Palladium, one of the world's rarest precious metals, is found in the earth's crust at about one part in 100 million, much rarer than gold. Only a few countries in the world, such as Russia and South Africa, produce less than 5 per cent of gold a year, making it rarer than platinum. Palladium is extremely tough, and jewelry made of palladium not only has the charming natural luster of platinum, but also withstands the test of time and remains as new as ever. Palladium has almost no impurities, is extremely pure and glows white. The purity of palladium is also good for the skin and does not cause skin irritation.
