The history of palladium bars is closely tied to the discovery and utilization of palladium as a precious metal. Palladium, a member of the platinum group metals, was discovered by the English chemist and physicist William Hyde Wollaston in 1803. However, it wasn’t until the early 20th century that palladium began to be used more widely.
The demand for palladium increased significantly in the mid-20th century due to its unique properties, including its ability to resist corrosion and oxidation. This led to the exploration and development of palladium mines, particularly in Russia and South Africa, which are major producers of platinum group metals.
