Precious metal recycling_ Introduction to palladium, a rare and precious metal

The historical origin of palladium:

Palladium is one of the precious metal elements, with the symbol Pd and Atomic number 46. It is a silver white transition metal with a soft texture and good plasticity, capable of forging, rolling, and drawing. Palladium has a bright silver white color, and its discoloration rate is very slow when exposed to air. It is the smallest density of all Platinum group and one of the rarest elements on the earth. Palladium has a relatively high melting point and can be used for various purposes.

In 1803, British chemist William Hyde Wollaston first separated palladium from palladium minerals. Palladium was named after the asteroid Pallas discovered two years ago. Today, palladium is mainly mined in Russia and South Africa, although there are also small amounts of palladium in North America, Europe, and Australia. It is estimated that there is only about 0.005 parts per million of palladium in the crust.

Application of palladium:

1. Historically, it was mined in Ancient Egypt, Greece and Rome and used to make coins and jewelry. Today, due to its aesthetic attraction and rarity, palladium is often used to make coins, medals and Commemorative coin.

2. Palladium is an important element in the production of catalytic converters. A catalytic converter is a device used to reduce pollutants in the automotive exhaust system. They contain palladium, which helps to convert harmful gases such as carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful gases. Palladium can also be used as a catalyst for the production of Hydrogen fuel cells and drugs and other compounds.

3. Palladium is also used in electronic products. It is used to manufacture electrical contacts, switches, and connectors. It is also used to manufacture capacitors, which are used to store electricity or produce jewelry, watches, and other luxury goods.

4. Palladium is also used in some medical applications, such as treating cancer and hypothyroidism. It has been found to be effective in reducing inflammation, increasing blood circulation, and preventing infection. People are still studying the potential of palladium in treating Alzheimer's disease.

Palladium is a widely used and valuable metal, and its use is constantly expanding with the development of new technologies. Palladium metal is highly corrosion-resistant, has good conductivity and thermal conductivity, and can be alloyed with other elements to create items with high strength and durability. Palladium has many unique properties, making it a popular element for industrial and commercial use and an important part of our lives. We have been innovating and developing new technologies for utilizing palladium, discovering its applications in other fields.
