- Rhodium was discovered in 1803 by William Hyde Wollaston, who also found palladium.
The name 'rhodium' comes from the Greek word 'rhodon', meaning 'rose', which refers to the rose color of some of its salts. It was discovered in 1803 by the English chemist William Hyde Wollaston. Wollaston isolated rhodium from platinum ore and recognized its potential due to its unique properties and resistance to corrosion. Initially, rhodium was used primarily for its catalytic properties and as a coloring agent in glass manufacturing. Over the years, its applications expanded significantly, particularly in the automotive industry and in jewelry making, due to its excellent reflective qualities and durability. Rhodium's rarity on Earth and significant demand have made it one of the most valuable precious metals today.
