Palladium reserves on the earth:
The reserves of palladium on the earth are scarce, and it is difficult to mine and smelt, which belongs to the series of rare and precious metals such as gold, silver, platinum, palladium, ruthenium and iridium. Palladium has good physical properties, stable chemical properties, is not easy to oxidize at room temperature, and has good corrosion resistance, but it will be corroded under specific medium and high temperature conditions. Appearance color, palladium presents a very elegant and clean white.
According to the current imitation market value, gold has the value of preserving value. Although palladium and platinum are rare and precious metals, palladium is rarely used in industry, so it has no value. But in recent years, the jewelry industry has used too much, and the price has been speculated.
